H.-F. Chen, Q. Fang and W.-T. Yu

Abstract: The title compound, [Ni(C₅O₅)(C₁₀H₈N₂)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 NiN₄O₂ coordination core basically adopts an octahedral geometry. The molecular twofold axis is along the direction of the molecular dipole moment, and the complex is packed with its dipole moment alternately along the +b and -b directions. The crystal structure is stabilized by intermolecular C-HO hydrogen bonds.
