[Pb2(2,2′-bipy)2(μ-4,4′-bipy)(NO3)4]: A novel hemidirected dimeric mixed-ligands lead(II) complex extended in holodirected two-dimensional polymer by weak Pb-Onitrate interactions

A novel PbII complex containing two different bipyridine ligands, [Pb2(2,2′-bipy)2(μ-4,4′-bipy)(NO3)4] has been synthesized and characterized by X-ray crystallography.
