Tetra-aqua-tetra-kis{μ(3)-3,3'-[(E,E)-ethane-1,2-diylbis(nitrilo-methyl-idyne)]benzene-1,2-diolato}octa-zinc(II) N,N-dimethyl-formamide hexa-solvate.

ABSTRACT: The asymmetric unit of the title compound [Zn(8)(C(16)H(12)N(2)O(4))(4)(H(2)O)(4)]·6C(3)H(7)NO, consists of eight Zn(II) cations, four tetra-valent anionic ligands, L(4-) (L(4-) = 3,3'-(1E,1'E)-(ethane-1,2-diylbis(azan-1-yl-1-yl-idene))bis-(methan-1-yl-1-yl-idene)dibenzene-1,2-bis-(olate), four coordinated water mol-ecules and six N,N-dimethyl-formamide solvate mol-ecules. The coordination complex comprises an octa-nuclear Zn(II) unit with its Zn(II) centers coordinated in two discrete distorted square-pyramidal geometries. Four Zn(II) atoms each coordinate to two nitro-gen atoms and two phenolate oxygen atoms from an individual L(4-) ligand and one coordinated water mol-ecule. The other four Zn(II) atoms each bind to five phenolate oxygen atoms from three different L(4-) ligands. In the c
