Abstract

The title compound, [Pd(2)(C(11)H(14)NO)(2)Cl(2)], has a dimeric structure with Cl atoms bridging the two Pd atoms, one half of the mol-ecule being generated by symmetry due to the crystallographic inversion centre located in the middle of the perfectly planar Pd(2)Cl(2) ring. The five-membered ring adopts an envelope conformation, while the morpholino group has a chair conformation. The geometry around the metal centres is distorted square-planar, as a result of a strong intra-molecular N→Pd coordination trans to a Pd-Cl bond. In the crystal structure, the dimeric structure is strengthened by inter-molecular C-H⋯Cl hydrogen bonds. C-H⋯C(phen-yl) inter-actions link the dimers into a columnar supra-molecular array along the a axis; the dimers are further connected by C-H⋯Ph inter-actions into a three-dimensional supra-molecular arrangement.

摘要

标题化合物[Pd₂(C₁₁H₁₄NO)₂Cl₂]具有二聚体结构,其中氯原子桥连两个钯原子,由于位于完美平面的Pd₂Cl₂环中心的晶体学倒转中心,分子的一半由对称性产生。五元环呈信封构象,而吗啉基团呈椅式构象。由于与Pd-Cl键反式的强分子内N→Pd配位作用,金属中心周围的几何形状为扭曲的平面正方形。在晶体结构中,二聚体结构通过分子间C-H⋯Cl氢键得到加强。C-H⋯C(苯基)相互作用将二聚体沿a轴连接成柱状超分子阵列;二聚体通过C-H⋯Ph相互作用进一步连接成三维超分子排列。
