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

Abstract

In the title compound, (C4H8N3O) 2[CdCl4], 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 [CdCl4]2- anions are sandwiched. The CdII 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. © 2009 Boufas et al.
