Poly[bis(phenethylammonium) [dibromidoplumbate(II)]-di-μ-bromido]]

Abstract

Crystals of the title compound, {(C6H5C2H4NH3)2[PbBr4]}n, were grown at room temperature from a solution in N,N-dimethylformamide (DMF) using nitromethane as the poor solvent. This perovskite-type organic–inorganic hybrid compound consists of well ordered sheets of corner-sharing disordered PbBr6 octahedra separated by bilayers of phenethylammonium cations. The octahedra are rotated and tilted due to N—H...Br hydrogen bonds with the ammonium groups, generating a superstructure in the unit cell similar to that of the tetrachloridoplumbate (C6H5C2H4NH3)2[PbCl4].
