We are interested in the preparation of organometallic tin compounds derived from biologically active molecules. One of the aims of our research is the structural analysis, particularly their coordination modes which has influence on their biological effects. The title compound (I) includes a ligand derived from quinoline and 2-aminophenol. It has been reported that quinoline-bearing structures show broad bio- logical activities such as antifungal (Musiol et al., 2006), anti- malarial (Nasveld & Kitchener, 2005), and antitumor (Rasoul- Amini et al., 2006). The activity of bis-quinolines as anti- leshmanial agents has also been reported through in vitro and in vivo studies (Palit et al., 2009). More recently, it has been shown that quinoline-based thiosemicarbazones present anti- tumor efficacy involving an iron chelation mechanism (Serda et al., 2012). In addition, Schiff bases derived from 8-hydroxyquinoline and its derivatives are well known for their ability towards the complexation of many metals (Charles & Perrotto, 1964; Corce´ et al., 2014; Albrecht et al., 2005, 2007). We report here the crystal structure of a new tin(IV) complex derived from a ligand produced from the 1:1 condensation of 8-hydroxyquinoline-2-carboxaldehyde and 2-aminophenol. The Schiff base H 2 L produced was complexed

cation is coordinated in a distorted tetrahedral geometry by two N atoms of a chelating 3,4,7,8-tetramethyl-1,10-phenanthroline ligand and two P atoms of two bridging 1,4-bis(diphenylphosphanyl)butane ligands, forming a 14-membered ring. An intramolecular – interaction stabilizes the conformation of the dication. In the crystal, dications are linked by – interactions involving adjacent phenanthroline rings, forming chains running parallel to [111]. Weak C—H F hydrogen interactions are also observed.

Each complex molecule forms three classical N—H Cl hydrogen bonds between the amine groups of the cyclam ligand in each complex cation and the Cl atoms of the tetra- chloridozincate anion, Table 1 (Steed & Atwood, 2009). These hydrogen bonds link the cations and anions into a three- dimensional network as shown in Fig. 3 and help to stabilize the crystal structure.

The crystal contains disordered methanol molecules as the packing solvent. Attempts to refine an adequate disordered solvent model failed, presumably due to the large number of molecules involved and the restraints required for an aniso- tropic refinement. Thus, the SQUEEZE procedure (Spek, 2015) of PLATON (Spek 2003, 2009) was used to delete the solvent contribution. This treatment decreased the R 1 value

Sulfones are good hydrogen-bond acceptors since their ability to participate as such in hydrogen-bonding interactions is increased by the highly polar nature of the sulfur–oxygen bond (Almarsson & Zaworotko, 2004; Eccles et al., 2010). In order to enrich the knowledge of such kinds of compound and to investigate the effect of hydrogen bonding on the chemical and structural features, we report here the synthesis and crystal structure analysis of a new salt of dapsone, the hydrated dinitrate 2C 12 H 14 N 2 O 2 S

4-methoxy--toluenethiolato [(4-methoxyphenyl)methanethiolato] units. One chlorido ligand and the p-cymene ligand complete the typical piano-stool coordination environment of the Ru II atom. In the crystal, the CH moiety of the chloroform molecule interacts with the chlorido ligand of the dinuclear complex, while one Cl atom of the solvent interacts more weakly with the methyl group of the bridging 4-methoxy--toluenethiolato unit. This assembly leads to the formation of supramolecular chains extending parallel to [021].

Crystal structure of bis p anizidinegossypol with an unknown solvate

Crystal structure of bis p anizidinegossypol with an unknown solvate

Gossypol [2,2 0 -bis(8-formyl-1,6,7-trihydroxy-5-isopropyl-3- methylnaphthalene)] is a yellow pigment of cotton seeds (Adams et al., 1960). This compound was first isolated over 110 years ago (Marchlewski, 1899). Its study was initially impor- tant because the compound is associated with anti-nutritive or even toxic effects when cottonseed is overfed to animals. Many attempts have been made to either remove it from cottonseed or reduce its toxicity (Kenar, 2006). However, the compound also has a wide range of biological action, including anti-HIV (Jian Yang et al., 2014), anticancer (Zhan et al., 2009) and antifertility (Coutinho, 2002) effects. This interest has led to the synthesis and isolation of various gossypol derivatives, including many diamine-based gossypol Schiff bases. Gossypol and its Schiff base formed with aniline have been previously reported to form inclusion compounds with many small organic compounds (Beketov et al., 1994; Gdaniec et al., 1996; Talipov et al. , 2004). Some gossypol polymorphs (referred to as the P3 polymorph; Ibragimov et al. , 1994), dianhydrogossypol (Talipov et al., 2009) and gossypol tetramethyl ether (Honkeldieva et al., 2015) form open-channel structures with channels of 5–8 A ˚ width. In this report, we demonstrate that the Schiff base of gossypol with p-anizidine also forms an open-channel structure when the compound is crystallized from solutions in dichloromethane.
