The title compound, {(C(8)H(20)N(2))[PbBr(4)]}(n), crystallizes as an inorganic-organic hybrid with alternating layers of diammonium cations and two-dimensional corner-sharing PbBr(6) octa-hedra extending parallel to the bc plane, which are eclipsed relative to one another. Both PbBr(6) octa-hedra and the organic cation exhibit symmetry. The cations inter-act via N-H⋯Br hydrogen bonding in the right-angled halogen sub-type of the terminal halide hydrogen-bonding motif.

Crystals of the title compound, {(C(6)H(5)C(2)H(4)NH(3))(2)[PbBr(4)]}(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 PbBr(6) 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 (C(6)H(5)C(2)H(4)NH(3))(2)[PbCl(4)].
