Bis{4-(all-yloxy)-N'-[4-(oct-yloxy)benzyl-idene]benzohydrazidato}nickel(II).

The central Ni(II) atom in the title complex, [Ni(C(25)H(31)N(2)O(3))(2)], is located on crystallographic inversion center and adopts a slightly distorted square-planar coordination geometry defined by the imine nitro-gen and amide oxygen donors of two chelating symmetry-related ligands in a trans configuration. The Ni-N and Ni-O bond lengths are 1.8685†(15) and 1.8409†(14)†à , respectively, with a chelating N-Ni-O bond angle of 83.79†(6)°. These data are in agreement with those determined for complexes of similar ligands.
