All interatomic distances in the title compound, C20H14N2O2S,
(I), are normal. The molecule consists of two cyclic moieties, an acridine and a substituted phenyl ring. The two rings are joinedviaa sulfur bridge [SÐC = 1.782 (3) and 1.764 (4) AÊ]. The substituted phenyl ring in (I) is nearly perpendicular to the acridine moiety, with a dihedral angle of 75.01 (7). The
acridine skeleton is slightly bent, with dihedral angles between the two terminal carbocyclic rings and the central heterocycle of 1.2 (1) and 0.5 (1). The molecules of the title compound
stack head-to-tail along theb axis, with a distance between molecules of about 4.381 AÊ. In order to investigate quantita-tively the aromaticity in acridines, we calculated the HOMA index [Krygowski (1993). J. Chem. Inf. Comput. Sci.33, 70.] for each of the acridine rings; values were 0.568 and 0.524 for the carbocyclic rings and 0.816 for the heterocycle.
Comment
Acridine derivatives are currently delivered to animals as antihelminthics agents (Durchheimeret al., 1980). In addition, acridine derivatives have shown in vitro activity against protozoan-like Trypanosoma cruzi (Ngadi et al., 1993) and
Leishmania donovani(Mesa-Valleet al., 1996). This work has been undertaken in the context of our studies on acridine derivatives with potential pharmacological properties (Karolak-Wojciechowskaet al., 1996; Karolak-Wojciechowska
et al., 1998). It was especially important to perform an X-ray analysis on single crystals of 9-(thio-2-methyl-4-nitrophenyl) acridine, (I), to obtain atomic coordinates which could be used as a starting point for further molecular modelling.
The molecular structure of (I) is presented in Fig. 1. The molecule consists of two cyclic moieties, an acridine and a substituted phenyl ring. The rings are joinedviaa sulfur bridge at C9 (S1ÐC9 = 1.782 (3) and S1ÐC10 = 1.764 (4) AÊ). The
substituted phenyl ring in (I) is nearly perpendicular to the acridine moiety, with a dihedral angle of 75.01 (7). The
molecules of (I) stack head-to-tail along the b axis, with a distance between molecules of about 4.381 AÊ. All bond distances and angles have normal values. The acridine

Agnieszka Mrozeket al. C20H14N2O2S Acta Cryst.(2002). E58, o1065±o1067 skeleton is slightly bent, with dihedral angles between the twoterminal carbocyclic rings,A1 andA3, and the heterocycleA2 of 1.2 (1) and 0.5 (1), respectively. As has been shown for
various hydrocarbon systems, such small deviations from planarity of an aromatic species do not affect the aromaticity signi®cantly (Krygowskiet al., 2000; Krygowski & Cyranski, 2001). It should also be noted that such a slight deformation of the acridine skeleton is in accordance with data for 34 C9-substituted acridines retrieved from the Cambridge Structural Database (Version of November 2001; Allen & Kennard, 1993). Most of these molecules include an acridine moiety with a very slight boat conformation. Only two structures found in the CSD contain acridine in a chair conformation. The average value of the dihedral angles between the terminal and central rings for the 34 molecules is 1.5. On account of
the interest in hydrocarbons and the aromaticity of their aza analogues (Krygowski et al., 2000; Krygowski & Cyranski, 2001), we decided to investigate quantitatively the aromaticity in acridines (Mrozek, Karolak-Wojciechowska, Amiel & Barbe, 2000a,b) by calculating the HOMA index (Krygowski, 1993) for each acridine ring in (I); its values are 0.568 and 0.524 for the carbocyclic rings, and 0.816 for the heterocycle. To con®rm these results, calculations of the HOMA index were performed for all 34 C9-substituted acridines found in the CSD (Set 1, HOMAAV= 0.744 and HOMAA2= 0.510), and
as, an extension of our statistical research, for 18 unsubstituted acridines (Set 2; HOMAAV= 0.810 and HOMAA2= 0.601) also
found in the CSD. For the terminal rings A1 and A3, the results of the HOMA calculations are given as an averaged
HOMA index (HOMAAV), whereas HOMAA2is the value of
the HOMA index for the central heterocyclic ring A2. The aromaticity of the central heterocycle is notably higher than for the terminal carbocyclic rings. A similar effect is observed, not only for the acridine parent molecule anthracene, where the HOMA index values are 0.638 for the terminal rings and 0.763 for the central one, but also for different aza-substituted benzenoids (Krygowski et al., 2000; Krygowski & Cyranski, 2001; Cyranski & Krygowski, 1996). Moreover, the replace-ment of CH by N usually leads to an increase in the aroma-ticity of the system. This conclusion is con®rmed by the fact that the HOMA indices for the central acridine ring are higher or, at least comparable to, those for anthracene.

As the collected data were relatively weak, there was a large proportion of re¯ections with low intensities, and thus some of the re¯ections were marked as unobserved. This affects the fraction of unique re¯ections observed (to= 80.91), which is equal to 62.6%.

S1. Comment
Acridine derivatives are currently delivered to animals as antihelminthics agents (Durchheimer et al., 1980). In addition, acridine derivatives have shown in vitro activity against protozoan-like Trypanosoma cruzi (Ngadi et al., 1993) and Leishmania donovani (Messa-Valle et al., 1996). This work has been undertaken in the context of our studies on acridine derivatives with potential pharmacological properties (Karolak-Wojciechowska et al., 1996; Karolak-Wojciechowska et al., 1998). It was especially important to perform an X-ray analysis on single crystals of 9-(thio-2-methyl-4-nitrophenyl) acridine, (I), to obtain atomic coordinates which could be used as a starting point for further molecular modelling. The
molecular geometry of(I) is presented in Fig. 1. The molecule consists of two cyclic moieties, an acridine and a phenyl
ring. The rings are joined via a sulfur bridge at C9 (S1—C9 = 1.782 (3) and S1—C1′ = 1.764 (4) Å). The phenyl ring in (I) is nearly perpendicular to the acridine moiety, with a dihedral of 75.01 (7)°. The molecules of (I) stack head-to-tail
along the y-axis, with a distance between molecules of about 4.381 Å. All bond distances and angles have typical values. The acridine skeleton is slightly bent, with dihedral angles between the two terminal carborings A1 and A3 and the
heterocycle A2 1.2 (1) and 0.5 (1)°, respectively. As has been shown for various hydrocarbon systems, such small
deviations from planarity of an aromatic species does not affect the aromaticity significantly (Krygowski et al., 2000; Krygowski & Cyranski, 2001). It should also be noted that such a slight deformation of the acridine skeleton is in
accordance with data for 34 C9-substituted acridines retrieved from the Cambridge Structural Database (Allen &

structures found in the CSD contain the acridine in a chair conformation. The average value of the dihedral angles
between the external and internal rings for the 34 molecules is 1.5°. Taking into consideration the interest in
hydro-carbons and the aromaticity of their aza analogues (Krygowski et al., 2000; Krygowski & Cyranski, 2001) we decided to investigate quantitatively the aromaticity in acridines (Mrozek,Karolak-Wojciechowska, Amiel & Barbe, 2000a,b) by calculating the HOMA index (Krygowski, 1993) for each acridine ring in (I); its values are 0.568 and 0.524 for the

all 34 C9-substituted acridines found in the CSD (Set 1; HOMAAV = 0.744 and HOMAA2 = 0.510) and as an extension of

additionally. For the terminal rings A1 and A3, the results of the HOMA calculations are given as an averaged HOMA

internal heterocycle is notably higher than for the external homorings. A similar effect is observed not only for the

Special details
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2,
conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used
only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2
are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
