摘要:
The title compound, [HgBr2(C10H8N2)](n), was obtained by mixing equimolar ethanolic solutions of mercuric bromide and 4,4'-bipyridine (4,4'-bipy). The bipy ligand acts as a linear bifunctional bridge forming a planar {-[Hg(4,4'-bipy)]-}(n) belt in the direction of the a axis. The remaining mercury coordination sites are occupied by Br- ions which link Hg centres in neighbouring belts via double bridges to form extended two-dimensional layers.
