Özet

The complex [Pb(H2O)(mu-OAc)(mu-sac)]n with acetate (OAc) and saccharinate (sac) ligands was characterized by IR, elemental analysis and X-ray crystallography The mixed-anion lead(II) complex crystallizes in the triclinic crystal system with the space group of P1. The single crystal X-ray analysis shows that the complex is a coordination polymer in which the lead(II) ions have a highly distorted pentagonal bipyramidal coordination geometry. Lead(II) ions are bridged by carboxylate groups in a zigzag arrangement forming one-dimensional infinite chains, which are also linked by sac bridges and aromatic pi-pi contacts between the adjacent phenyl rings of sac ligands, resulting in a three-dimensional network. One water molecule coordinates the lead(II) ion and also forms weak hydrogen bonds with the sulfonyl oxygen atoms of the neighboring sac ligands. The sac ligand acts as a bridging ligand through the nitrogen and carbonyl oxygen atoms, while the carboxylate moiety of the acetate ligand shows an unusual (bidentate, and bridging) coordination behaviour, which was observed for the first time in the structure.
