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.
