Bis[-2-hydroxy-N'-(4-hydroxy-2-oxidobenzylidene)benzohydrazide]bis[pyridinezinc(II)] dimethylformamide disolvate

J.-S. Huang and M.-T. Li

Abstract: Reaction of 2,4-dihydroxybenzaldehye salicylhydrazide (L) with Zn(OAc)₂·2H₂O in a mixed solvent of pyridine and N,N-dimethylformamide (DMF) resulted in the formation of the title complex, [Zn₂(C₁₄H₁₀N₂O₄)₂(C₅H₅N)₂]·2C₃H₇NO. The asymmetric unit contains one complete neutral zinc complex and one-half of a second complex with crystallographic inversion symmetry, together with three DMF solvent molecules. The Zn atoms, all having the same coordination geometry, are coordinated by three O atoms and two N atoms in a distorted tetragonal-pyramidal geometry, with phenolate O atoms acting as bridges between the Zn atoms.
