Synthesis and crystal structure of a novel 2-D hybrid compound [(PbBr2)2(μ-Pyz)]n (Pyz=pyrazine)

A novel 2-D organic–inorganic hybrid compound [(PbBr2)2(μ-Pyz)]n 1, has been prepared, and its X-ray structure shows that the supramolecular structure consists of organic–inorganic hybrid layers, each of which is constructed from two [PbBr2]n sheets and one pyrazine, via Pb–N bonding along the direction of the b-axis, and the divalent lead is penta-coordinated to form a hemidirected complex.
