The title compound, [RuCl(CH)(CHOP)] (), crystallizes in the monoclinic space group 2/ with two crystallographically independent mol-ecules ( and ) in the asymmetric unit. The geometries of both mol-ecules are very similar and distinguished only by the twist angles of the two benzene rings in the phosphine substituents [89.54 (14) and 78.36 (14)° for mol-ecules and , respectively]. The Ru atoms have classical pseudo-tetra-hedral piano-stool coordination environments. The conformation of each mol-ecule is stabilized by intra-molecular C-H⋯O and C-H⋯Cl hydrogen bonds and C-H⋯π inter-actions. The two mol-ecules are linked by a C-H⋯Cl hydrogen bond. In the crystal, the mol-ecules are further linked by C-H⋯ π inter-actions, forming ----- chains propagating along the -axis direction. Complex is an active catalyst for reductive amination reaction. The catalytic activity of this complex can be explained by the lability of the -cymene ligand, which can be replaced by two-electron ligands such as CO or amine.
标题化合物[RuCl(CH)(CHOP)]（）以单斜晶系空间群2/结晶，不对称单元中有两个晶体学独立的分子（和）。两个分子的几何结构非常相似，仅通过膦取代基中两个苯环的扭转角来区分[分子和分别为89.54 (14)°和78.36 (14)°]。Ru原子具有经典的伪四面体钢琴凳配位环境。每个分子的构象通过分子内C-H⋯O和C-H⋯Cl氢键以及C-H⋯π相互作用得以稳定。两个分子通过C-H⋯Cl氢键相连。在晶体中，分子进一步通过C-H⋯π相互作用相连，形成沿轴方向传播的-----链。配合物是还原胺化反应的活性催化剂。该配合物的催化活性可以通过对异丙基苯配体的不稳定性来解释，它可以被诸如CO或胺等双电子配体取代。
