Abstract: The title compound, (C₁₃H₂₈N₂)₂[Zn₂(C₈H₄O₄)Cl₆]·4H₂O, was prepared by the reaction of ZnCl₂·6H₂O, benzene-1,4-dicarboxylic acid and 4,4'-diaminodicyclohexylmethane in methanol. The [Zn₂Cl₆(C₈H₄O₄)]^4- anions lie on centres of inversion and comprise two ZnCl₃ groups bridged by benzene-1,4-dicarboxylate. In addition to N-HCl and N-HO hydrogen bonds between the cations and anions, solvent water molecules form O-HO and O-HCl hydrogen bonds to give a three-dimensional network.
