The title compound, [Pt(C12H27P)2(C14H8N)2], is a mono-nuclear PtII di-yne exhibiting -conjugation along the molecular backbone. It is used as a model species for rigid-rod platinum poly yne compounds of which it is a precursor. Such compounds are of interest due to the extended -conjugation through the hetero-aromatic linker unit in the backbone.

Comment

Here we report the structural characterization of the title compound, (I), which is a mononuclear platinum(II) di-yne species, trans-[Pt(PnBu

3)2(ÐC CR)2] (R = carbazol-3-yl). Such platinum-containing species form the building blocks for rigid-rod organometallic poly-ynes of general formulatrans -[Pt(PnBu

3)2ÐC CÐRÐC CÐ]1 (R = aromatic or a

heteroaromatic linker unit). Platinum(II) poly-ynes are of immense current interest due to-electron conjugation along the backbone, donor±acceptor metal±ligand interactions and novel photophysical properties (Wittmann et al., 1994; Beljonne et al., 1996; Younus et al., 1998; Chawdhury et al., 1998, 1999; Khan, Al-Mandhary, Al-Suti, Hisahmet al., 2002; Khan, Al-Mandhary, Al-Suti, Feeder et al., 2002; Khan, Al-Mandhary, Al-Suti, Corcoranet al.2003; Khan, Al-Sutiet al., 2003; Khan, Al-Mandhary, Al-Suti, Ahrenset al., 2003). They possess interesting opto-electronic properties useful for application in light-emitting diodes and photocells (Wilsonet al., 2000; Wilson, Chawdhuryet al., 2001; Wilson, Dhootet al., 2001). Precursors to these species, such as the title compound, are studied as models of the molecular and electronic prop-erties and structure±property relationships in the metal poly-ynes.

The structure of (I) exhibits a CÐH N close contact between the alkyl H atom H25A and nitrogen N1, with a C25 N1 distance of 3.674 (5) AÊ (Table 2).

Experimental

The title compound was synthesized by the following procedure. To a stirred solution of trans-[(PnBu

3)2PtCl2] (0.38 g, 0.5 mmol) and

3-ethynylcarbazole (0.19 g, 1.0 mmol) in CH2Cl2/iPr2NH (50 ml, 1:1v/v)

under nitrogen was added a catalytic amount of CuI (5 mg). The

(2)

yellow solution was stirred at room temperature for 15 h, after which all volatile components were removed under reduced pressure. The residue was dissolved in CH2Cl2and passed through a silica column

eluting with hexane/CH2Cl2(1:1,v/v). Removal of the solvents under

vacuo gave the title complex as a pale-yellow solid in 72% yield.

S1. Comment

In this paper, we report the structural characterization of the title compound, (I), which is a mononuclear platinum(II)

di-yne species, trans-[Pt(PnBu

3)2(—C≡CR)2] (R = carbazol-3-yl). Such platinum-containing species form the building blocks

for rigid-rod organometallic poly-ynes of general formula trans-[Pt(PnBu

3)2—C≡C—R—C≡C—]∞ (R = aromatic or

heteroaromatic linker unit). Platinum(II) poly-ynes are of immense current interest due to π-electron conjugation along

the backbone, donor–acceptor metal–ligand interactions and novel photophysical properties (Wittmann et al., 1994;

Beljonne et al., 1996; Younus et al., 1998; Chawdhury et al., 1998, 1999; Khan et al., 2002, 2003). They possess

interesting optoelectronic properties useful for application in light-emitting diodes and photocells (Wilson et al., 2000,

2001). Precursors to these species, such as the title compound, are studied as models of the molecular and electronic

properties and structure-property relationships in the metal poly-ynes.

The structure of (I) exhibits a C—H···N close contact between alkynyl atom H25a and N1, with a C25···N1 distance of

3.674 (5) Å (Table 2).

S2. Experimental

The title compound was synthesized by the following procedure. To a stirred solution of trans-[(PnBu

3)2PtCl2] (0.38 g, 0.5

mmol) and 3-ethynylcarbazole (0.19 g, 1.0 mmol) in CH2Cl2/iPr2NH (50 ml, 1:1 v/v) under nitrogen was added a catalytic

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.
