[N′-(1,3-Dioxoindan-2-ylidene)-2-oxidobenzohydrazidato-κ3O2,N,O]tripyridinenickel(II) pyridine solvate

Abstract

In the title compound, [Ni(C16H8N2O4)(C5H5N)3]·C5H5N, the NiII atom is six-coordinated by two O atoms and one N atom from the Schiff base ligand and by three N atoms from three pyridine molecules, forming a distorted octahedral geometry. The Ni—O(phenolate) bond [1.9750 (16) Å] is shorter than the Ni—O(carbonyl) bond [2.0840 (16) Å] and the Ni—N bonds (mean 2.120 Å).
