The asymmetric unit of the title compound, [PtCl(4)(C(12)H(8)N(2))]·0.5CH(3)CN, contains two crystallographically independent Pt(IV) complexes with very similar geometry and one solvent mol-ecule. In the complexes, each Pt(IV) ion is six-coordinated in a distorted octa-hedral environment by two N atoms of the 1,10-phenanthroline ligand and four Cl atoms. Because of the different trans effects of the N and Cl atoms, the Pt-Cl bonds trans to the N atom are slightly shorter than those trans to the Cl atom. The compound displays numerous inter-molecular π-π inter-actions between six-membered rings, with a shortest centroid-to-centroid distance of 3.654 Å. There are also weak intra- and inter-molecular C-H⋯Cl hydrogen bonds.
标题化合物[PtCl₄(C₁₂H₈N₂)]·0.5CH₃CN的不对称单元包含两个晶体学独立的Pt(IV)配合物，其几何结构非常相似，还有一个溶剂分子。在配合物中，每个Pt(IV)离子在扭曲的八面体环境中通过1,10 - 菲咯啉配体的两个N原子和四个Cl原子进行六配位。由于N和Cl原子的反位效应不同，与N原子反位的Pt - Cl键比与Cl原子反位的Pt - Cl键略短。该化合物在六元环之间显示出大量分子间π - π相互作用，质心到质心的最短距离为3.654 Å。还存在弱的分子内和分子间C - H⋯Cl氢键。
