A complex with eight-coordinate lead(n) atom and saccharinate (sac) and 2-aminomethylpyridine ligands was characterized by IR, elemental analysis and X-ray crystallography. The lead(II) complex crystallizes in the monoclinic crystal system with space group P2(1)/c. The single crystal X-ray analysis shows that the complex is a coordination polymer, [Pb(ampy)(mu-sac)(2)](n), in which the lead(II) ions have a highly distorted bicapped trigonal antiprism coordination. Lead(II) ions are bridged by carboxyl groups of sac forming one-dimensional linear chains, running parallel to the a axis. The intrachain Pb... Ph distances are 4.4490(3) and 4.4679(3) Angstrom. The individual chains are connected by N-H...O-sulfonyl and C-ampy-H...O-sulfonyl type hydrogen bonds, resulting in a three-dimensional network. The sac ligand acts as bidentate and bridging ligand, while ampy behaves as an N,N' donor. The IR spectra of the lead(II) complex are discussed in detail.
