Abstract

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.
