(2-Meth-oxy-benz-yl)(2-meth-oxy-benzyl-idene)aza-nium (2-meth-oxy-phen-yl)methanaminium tetra-chloridozincate(II) monohydrate.

The title compound, (C(8)H(12)NO)(C(16)H(18)NO(2))[ZnCl(4)]·H(2)O, was obtained as a by-product of the Zn(2+) and HCl catalyzed condensation of (2-meth-oxy-phen-yl)methanamine in water. Both cations feature an intra-molecular N-H⋯O hydrogen bond. In the crystal, the components are linked by an extensive three-dimensional network of N-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds (three of them bifurcated). Weak C-H⋯O intera-ctions also occur.
