The title compound, [Ni(C(5)O(5))(C(10)H(8)N(2))(2)], lies across a crystallographic twofold axis, around which two 2,2'-bipyridine (2,2'-bipy) ligands are arranged in a propeller manner. The local geometry of the NiN(4)O(2) coordination core basically adopts an octa-hedral geometry. The mol-ecular twofold axis is along the direction of the mol-ecular dipole moment, and the complex is packed with its dipole moment alternately along the +b and -b directions. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.
标题化合物[Ni(C₅O₅)(C₁₀H₈N₂)₂]位于一个晶体学二重轴上,围绕该轴两个2,2'-联吡啶(2,2'-bipy)配体呈螺旋状排列。NiN₄O₂配位核心的局部几何构型基本采用八面体几何构型。分子二重轴沿分子偶极矩方向,该配合物的偶极矩沿+b和-b方向交替堆积。晶体结构通过分子间C—H⋯O氢键得以稳定。
