Tetra­aqua­tetra­kis{μ(3)-3,3′-[(E,E)-ethane-1,2-diylbis(nitrilo­methyl­idyne)]benzene-1,2-diolato}octa­zinc(II) N,N-dimethyl­formamide hexa­solvate

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 tetra­valent anionic ligands, L (4−) (L (4−) = 3,3′-(1E,1′E)-(ethane-1,2-diylbis(azan-1-yl-1-yl­idene))bis­(methan-1-yl-1-yl­idene)dibenzene-1,2-bis­(olate), four coordinated water mol­ecules and six N,N-dimethyl­formamide solvate mol­ecules. The coordination complex comprises an octa­nuclear Zn(II) unit with its Zn(II) centers coordinated in two discrete distorted square-pyramidal geometries. Four Zn(II) atoms each coordinate to two nitro­gen atoms and two phenolate oxygen atoms from an individual L (4−) ligand and one coordinated water mol­ecule. The other four Zn(II) atoms each bind to five phenolate oxygen atoms from three different L (4−) ligands. In the crystal structure, the Zn(II) complex unit, coordinated water mol­ecules and dimethyl­formamide solvate mol­ecules are linked via O—H⋯O and C—H⋯O hydrogen bonds. Mol­ecules are connected by additional inter­molecular O—H⋯O and C—H⋯O hydrogen bonds, forming an extensive three dimensional framework.
