Abstract
The title compound, poly[bis-(β-alaninium) [[di-bromido-plumbate]-di-μ-di-bromido]] {(C2H8NO2)2[PbBr4]} n or (β-AlaH)2PbBr4, crystallizes in the monoclinic space group P21/n. The (PbBr4)2- anion is located on a general position and has a two-dimensional polymeric structure. The Pb center is holodirected. The supra-molecular network is mainly based on O-H⋯Br, N-H⋯Br and N-H⋯O hydrogen bonds.
