Bis[O-isopropyl (4-eth-oxy-phen-yl)dithio-phospho-nato-κ(2) S,S']lead(II).

ABSTRACT: The title compound, [Pb(C11H16O2PS2)2], is a neutral four-coordinate mononuclear complex with a distorted square-pyramidal geometry of the PbS4 core. The apical Pb(II) atom of each pyramid is 1.33059 (3) Å above the basal S4 plane. The metal atom is surrounded by two chelating dithio-phospho-nate ligands binding through the S-donor atoms. The ligands are anisobidentate as the pyramid is comprised of Pb-S bond lengths that vary substanti-ally [2.6999 (7), 2.7128 (6), 2.8877 (7) and 2.9472 (7) Å], clearly indicating two short and two longer bond lengths. The P-S bond lengths are also paired as shorter [1.9959 (9) and 1.9877 (8) Å] and slightly longer [2.0115 (9) and 2.0245 (9) Å], indicating an anisobidentate nature of the ligand whereby the shorter P-S bond has more double-bond character th
