Poly[[tris(mu(2)-acetato-kappa O-2:O')(4-chlorobenzene-1,2-diamine-kappa N)(mu(3)-hydroxido)-dizinc] ethanol monosolvate]

The title compound, {[Zn-2(CH3CO2)(3)(OH)(C6H7ClN2)]center dot 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 center dot center dot center dot O hydrogen bonds form between the hydroxide ligand and the ethanol solvent molecule. N-H center dot center dot center dot O and N-H center dot center dot center dot N hydrogen bonding between the uncoordinated amine group and the acetate ligands and the coordinated amine group are also observed.
