Özet

The coordination around the Ni atom in the title compound, {2,2'-[2,3-pyridinediylbis(iminomethyl-N)]diphenolato-O,O')nickel(II), [Ni(C19H13N3O2)], is slightly distorted from square planar. Within the coordination square, the bond angles are in the range 83.8(1)-, 94.8(2)degrees, The Ni-N and Ni-O distances are equal within experimental error, with average values of 1.854(2) and 1,835(2) Angstrom, respectively. Comparison of bond lengths in free and nickel-coordinated ligands indicates a shortening of the C-O bonds due to packing effects. On complex formation, the whole molecule assumes a more planar form, which brings the Ni atoms of neighbouring molecules as close as 3.1908(10) Angstrom to each other.
