Bis{μ-N-(E)-4-benz­yloxy-2-oxidobenzyl­idene-4-nitro­benzene­carbo­hydrazidato}bis­di­aqua­nickel(II) di­methyl­formamide tetra­solvate

摘要

The molecule of the title complex, [Ni2(C21H15N3O5)2(H2O)4]·4C3H7NO, is located on an inversion centre. This results in a dimeric Ni^II complex, with the two Ni^II atoms bridged by phenolate O atoms. The tridentate ligand is chelated to each Ni^II atom via one N and two O atoms of the imino­late form of the hydrazide moiety, which has the same conformation as the free ligand. The coordination geometry around each Ni^II ion is slightly distorted octa­hedral. A supra­molecular three-dimensional architecture is created by dominant inter­molecular O—H⋯N, O—H⋯O and C—H⋯O hydrogen-bonding inter­actions. These are augmented by two C—H⋯π inter­actions and a π–π inter­action with a centroid–centroid distance of 3.681 (2) Å.
