The title compound, [PtCl(CHP)]·2CHCl (I), is the third monoclinic polymorph of this platinum(II) complex involving the bidentate ligand -1,2-bis-(di-phenyl-phosphan-yl)ethyl-ene (-dppe) [for the others, see: Oberhauser (1998 ▸). , , 143-154, and Oberhauser (1995 ▸). , , 35-43]. The structure of compound (I) was solved in the space group 2/, with one complex mol-ecule in the asymmetric unit along with two solvate chloro-form mol-ecules. The Pt atom is ligated by two P and two Cl atoms in the equatorial plane and has a perfect square-planar coordination sphere. In the crystal, the complex mol-ecule is linked to the chloro-form solvate mol-ecules by C-H⋯Cl hydrogen bonds and face-on C-Cl⋯π inter-actions. There are also weak offset π-π inter-actions present [inter-centroid distances are 3.770 (6) and 4.096 (6) Å], linking the mol-ecules to form supra-molecular sheets that lie in the plane.
标题化合物[PtCl(CHP)]·2CHCl (I)是该铂(II)配合物的第三种单斜多晶型物，涉及双齿配体-1,2-双(二苯基膦基)乙烯(-dppe) [其他的见：Oberhauser (1998 ▸).,, 143 - 154,以及Oberhauser (1995 ▸).,, 35 - 43]。化合物(I)的结构在空间群2/中解析，不对称单元中有一个配合物分子以及两个溶剂化氯仿分子。Pt原子在赤道平面上被两个P原子和两个Cl原子配位，具有完美的平面正方形配位球。在晶体中，配合物分子通过C—H⋯Cl氢键和面对面的C—Cl⋯π相互作用与氯仿溶剂化分子相连。还存在弱的错位π - π相互作用[质心间距为3.770 (6)和4.096 (6) Å]，将分子连接形成位于 平面的超分子片层。
