Abstract

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 octahedral coordination polyhedron. By corner-sharing of the [CdCl6] octahedra, 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 interactions.
