Poly[bis(phenethyl-ammonium) [di-bromido-plumbate(II)]-di-μ-bromido]]

Abstract

Crystals of the title compound, {(C6H5C 2H4NH3)2[PbBr4]} n , were grown at room temperature from a solution in N,N-dimethyl-formamide (DMF) using nitro-methane as the poor solvent. This perovskite-type organic-inorganic hybrid compound consists of well ordered sheets of corner-sharing disordered PbBr6 octa-hedra separated by bilayers of phenethyl-ammonium cations. The octa-hedra 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 tetra-chloridoplumbate (C6H5C 2H4NH3)2[PbCl4].
