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.
