Bis[O-isopropyl (4-eth-oxy-phen-yl)dithio-phospho-nato-?(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 than the other. The S-Pb-S (chelating) bond angles range from 71.841?(18) to 72.692?(19)°, whilst the Pb-S-P bond angles range from 84.70?(3) to 90.51?(3)°.
