Poly[bis-(O-ethyl-hydroxy-laminium) [di-µ-chlorido-di-chlorido-cadmate(II)]].

The title compound, {(CH3CH2ONH3)2[CdCl4]}n, consists of bilayers of organic CH3CH2ONH3 + cations and infinite [CdCl4]n 2n- inorganic layers. It can be described as an organic-inorganic hybrid layered perovskite. In the crystal structure, the CdII cation is situated at an inversion center and is coordinated by six chloride ions, forming a slightly distorted octa-hedral coordination polyhedron. By corner-sharing of the [CdCl6] octa-hedra, infinite [CdCl4]n 2n- inorganic layers are formed, extending parallel to (100). The inorganic layers alternate with bilayers of CH3CH2ONH3 + cations, whereby the connection of the cationic and anionic layers is achieved through N-H⋯Cl hydrogen bonds and Coulombic inter-actions.
