Bis(creatininium) tetra-chlorido-cadmate(II).

In the title compound, (C(4)H(8)N(3)O)(2)[CdCl(4)], the asymmetric unit comprises two creatininium cations and one tetra-chloridocadmate anion. Cd⋯O secondary bonding links one of the two imidazole rings and the anion into ion pairs. The free and bound cations form layers between which the [CdCl(4)](2-) anions are sandwiched. The Cd(II) atom adopts a distorted trigonal-bipyramidal geometry in which the Cd⋯O bond is axial. Inter-molecular N-H⋯Cl hydrogen bonds form a two-dimensional network parallel to (001) which ensures the junction between creatininium cations and [CdCl(4)](2-) anions.
