Poly[[tris-(μ2-acetato-κ(2) O:O')(4-chloro-benzene-1,2-di-amine-κN)(μ3-hydroxido)dizinc] ethanol monosolvate

Abstract

The title compound, {[Zn2(CH3CO2)3(OH)(C6H7ClN2)]·C2H5OH}n, has alternating octa­hedrally and tetra­hedrally coordinated Zn2+ ions. The octa­hedral coordination sphere is composed of one N atom of the monodentate di­amino­chloro­benzene ligand, three acetate O atoms and two bridging hydroxide ligands. The tetra­hedral coordination sphere consists of three acetate O atoms and the hydroxide ligand. The zinc ions are bridged by acetate and hydroxide ligands. The result is a laddered-chain structure parallel to [100] with ethanol solvent mol­ecules occupying the space between the chains. The di­amine ligand chlorine substitutent is disordered over two equally populated positions as a result of a crystallographically imposed inversion center between adjacent ligands. The ethanol solvent mol­ecule exhibits disorder with the two components having refined occupancies of 0.696 (11) and 0.304 (11). O—H⋯O hydrogen bonds form between the hydroxide ligand and the ethanol solvent mol­ecule. N—H⋯O and N—H⋯N hydrogen bonding between the uncoordinated amine group and the acetate ligands and the coordinated amine group are also observed.
