Bis[?-O-isopropyl (4-eth-oxy-phen-yl)dithio-phospho-nato-?(2) S:S']bis-{[O-iso-propyl (4-eth-oxy-phen-yl)dithio-phos-phonato-?(2) S,S']mercury(II)}.

ABSTRACT: The title compound, [Hg2(C11H16O2PS2)4], is a dinuclear complex with a distorted tetra-hedral geometry around each Hg(II) atom. Although the two Hg(II) atoms are surrounded by the same ligand, two different coordination modes are observed: one is chelating and the other bridging. The Hg-S bonds form two distinct pairs of long and short bonds. One pair includes both chelating and bridging Hg-S bonds with approximately equal bond lengths of 2.4042?(8) and 2.3997?(7)?Å, respectively. The other pair is significantly longer at 2.9361?(9) and 2.8105?(8)?Å, respectively. This pattern forms a center of inversion through the mol-ecule with an equal and opposite effect occurring at the other Hg(II) atom. The S-Hg-S angles vary widely from 76.26?(2) to 154.65?(3)°, indicative of a distorted tetra-hedral arrangement of the S atoms around the Hg(II) atom. The P-S bond lengths are 1.9681?(10) and 2.0519?(11)°, clearly indicating partial double-bond character in the former. The mol-ecule contains an inversion center situated between the two Hg(II) atoms.
