Poly[[tris-(?2-acetato-?(2) O:O')(4-chloro-benzene-1,2-di-amine-?N)(?3-hydroxido)dizinc] ethanol monosolvate].

ABSTRACT: The title compound, {[Zn2(CH3CO2)3(OH)(C6H7ClN2)]·C2H5OH} n , has alternating octa-hedrally and tetra-hedrally coordinated Zn(2+) ions. The octa-hedral coordination sphere is composed of one N atom of the monodentate di-amino-chloro-benzene ligand, three acetate O atoms and two bridging hydroxide ligands. The tetra-hedral 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 mol-ecules occupying the space between the chains. The di-amine 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 mol-ecule 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 mol-ecule. 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.
