A one-dimensional mixed-anion lead(II) coordination polymer: catena-poly[[(1,10-phenanthroline)lead(II)]-mu-benzoato-mu-nitrato-[(1,10-phenanthroline)lead(II)]-di-mu-benzoato].

In the title polymeric compound, [Pb2(C7H5O2)3(NO3)(C12H8N2)2]n, both independent Pb atoms adopt an eight-coordinate geometry formed by one nitrate, three benzoate and one 1,10-phenanthroline ligand. The one-dimensional polymer consists of dimeric [Pb2(C7H5O2)3(NO3)(C12H8N2)2] units, in which all nitrate and benzoate ligands act in a bridging-chelating coordination mode.
