The crystal structure of the title compound, [PtCl(2)(C(25)H(22)NPS)]·0.5CH(2)Cl(2), was determined to establish the coordination properties of the (phosphan-yl)benzyl-idene-methanamine ligand to platinum. In the unit cell two mol-ecules of cis-[PtCl(2)(C(25)H(22)NPS)] are accompanied by a dichloro-methane solvent mol-ecule. The square-planar Pt(2+) coordination sphere is slightly distorted with the bidentate ligand coordinated via the P and the amine N atoms, and the Cl atoms located cis at the two remaining coordination sites. Parts of the thiophene ring and the solvate molecule were modeled as disordered with occupancy ratios of 0.55 (2):0.45 (2) and 0.302 (10):0.198 (10), respectively. Weak C-H⋯Cl inter-actions stabilize the crystal packing.
测定了标题化合物[PtCl₂(C₂₅H₂₂NPS)]·0.5CH₂Cl₂的晶体结构，以确定(膦亚基)苄叉甲胺配体与铂的配位性质。在晶胞中，两个顺式[PtCl₂(C₂₅H₂₂NPS)]分子伴随着一个二氯甲烷溶剂分子。平面正方形的Pt²⁺配位球略有扭曲，双齿配体通过P和胺N原子配位，Cl原子位于其余两个配位位点的顺式位置。噻吩环的部分和溶剂化物分子被模拟为无序，占有率分别为0.55(2):0.45(2)和0.302(10):0.198(10)。弱C-H⋯Cl相互作用稳定了晶体堆积。
