[2,3-Bis(salicylideneamino-O,N)pyridinato]nickel(II)

The coordination around the Ni atom in the title compound, {2,2'-[2,3-pyridindiylbis(iminomethyl)]diphenolato}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)°. The Ni-N and Ni-O distances are equal within experimental error with average values of 1.854 (2) and 1.835 (2) Å, respectively. Comparisons of bond lengths in free and Ni-coordinated ligands indicate shortening of the C-O bonds due to the packing effect. On complex formation, the whole molecule assumes a more planar form, which brings the Ni atoms from neighbouring molecules as close as 3.1908 (10) Å to each other.
