In the title compound, [PtCl₂(C₁₈H₁₅P)₂]·CHCl₃, each Pt^II centre adopts a nearly square-planar coordination geometry formed by two P atoms [Pt—P = 2.2481 (17) and 2.2658 (19) Å] and two Cl anions [Pt—Cl = 2.3244 (19) and 2.3548 (17) Å]. The Cl atoms of the chloroform solvent molecule are disordered over two orientations in a 0.778 (11):0.222 (11) ratio. The crystal packing is stabilized by weak intermolecular C—H⋯Cl hydrogen bonds, exhibiting voids with a volume of 215 Å³.

Comment top

cis- and trans-Dichloridobis (triphenylphosphine)platinum(II) are useful to prepare other platinum complexes. The structures of the cis-isomer, either in unsolvated form (Fun et al., 2006) or as an acetone (Anderson et al., 1982) or trichoroform solvate (Al-Fawaz et al., 2004) have been reported. During the course of our studies on platinaborane cluster compounds using the cis-isomer as a starting material, we unexpectedly obtained the yellowish crystals of the title compound (I).

As shown in Fig.1, the platinum centre is four-coordinated and adopts a nearly square planar geometry. The Pt—P bond lengths (2.2481 (17) and 2.2658 (19) Å) and Pt—Cl bond lengths (2.3244 (19) and 2.3548 (17) Å), as well as the bond angles around the Pt atom are similar to those in the above-mentioned structures.

Intermolecular C—H···Cl hydrogen bonding is observed between the chloroform and the chloride (Table 1). Moreover, similar C—H···Cl interaction between one of the phenyl groups and the chloride (Table 1) links the molecules into a one-dimensional chain structure.

Experimental top

A mixture of PtCl₂(PPh₃)₂ (314 mg, 0.4 mmol) and (Et₄N)₂B₁₀H₁₀ (150 mg, 0.4 mmol) in HOCH₂CH₂OH (38 ml) was heated at 100°C (oil) under N₂ atomosphere for 39 h. The resulting mixture was filtered to get a red filtrate, to which ca 400 ml of water was added. The lower layer formed was separated and treated with water. This process was repeated till the lower layer was colourless. The upper water phase combined was extracted with CH₂Cl₂. The yellow organic layer was dried to result in a reddish solid. Recrystalization in CHCl₃/n-hexane(1:4, V: V) afforded a small amount of yellowish crystals of the title compound suitable for X-ray analysis.
