Bis(2,2′-bipyridine-κ(2) N,N′)(croconato-κ(2) O,O′)nickel(II)

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 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—H⋯O hydrogen bonds.
