Sumario: | The asymmetric unit of the title compound, tetraaquatetrakis{μ(3)-6,6′-dioxido-2,2′-[1,2-phenylenebis(nitrilomethylidyne)]diphenolato}octazinc(II) dimethyl sulfoxide tetrasolvate dihydrate, [Zn(8)(C(20)H(12)N(2)O(4))(4)(H(2)O)(4)]·4C(2)H(6)OS·2H(2)O, contains one quarter of a Zn(II) octanuclear complex with [Image: see text] symmetry, one dimethyl sulfoxide molecule and one half of a water molecule which lies on a twofold rotation axis. The Zn(II) atoms of the octanuclear complex have two different five-coordinate environments, viz. ZnN(2)O(3) and ZnO(5). All eight Zn(II) centers adopt a distorted square-pyramidal coordination; four Zn(II) ions have the N(2)O(2) tetradentate Schiff base ligand bound in a basal plane and the coordinated water molecule occupying the apical site, while the remaing four Zn(II) ions are bound by five O atoms from three Schiff base ligands. In the crystal structure, Zn(II) complex molecules, coordinated and uncoordinated water molecules and dimethyl sulfoxide molecules are linked via O—H⋯O and C—H⋯O hydrogen bonds and C—H⋯π interactions, forming a three-dimensional framework. |
