Abstract
The title compound, [Hg2(C11H16O2PS2)4], is a dinuclear complex with a distorted tetrahedral geometry around each HgII atom. Although the two HgII 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 molecule with an equal and opposite effect occurring at the other HgII atom. The S—Hg—S angles vary widely from 76.26 (2) to 154.65 (3)°, indicative of a distorted tetrahedral arrangement of the S atoms around the HgII atom. The P—S bond lengths are 1.9681 (10) and 2.0519 (11)°, clearly indicating partial double-bond character in the former. The molecule contains an inversion center situated between the two HgII atoms.

Summary
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) A , respectively. The other pair is significantly longer at 2.9361 (9) and 2.8105 (8) A , respectively. This pattern forms a center of inversion through the molecule with an equal and opposite effect occurring at the other HgII atom. The S—Hg—S angles vary widely from 76.26 (2) to 154.65 (3), indicative of a distorted tetrahedral arrangement of the S atoms around the HgII atom.
