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-HBr hydrogen bonds with the ammonium groups, generating a superstructure in the unit cell similar to that of the tetrachloridoplumbate (C₆H₅C₂H₄NH₃)₂[PbCl₄].
