Crystal structure of bis(β-alaninium) tetrabromidoplumbate

This work focused on characterizing the structure from a stereochemical point of view, discussing the Pb^II character. The XRD data were collected at 200 K.

The title compound, poly[bis(β-alaninium) [[dibromidoplumbate]-di-μ-dibromido]] {(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 supramolecular network is mainly based on O—H⋯Br, N—H⋯Br and N—H⋯O hydrogen bonds.

期刊介绍： Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
