Abstract

In the title compound, [Pb(C14H14O2PS2)2]n, the metal atom is surrounded by two O,O′-bis­(2-methyl­phen­yl) dithio­phosphate ligands bonding through the S-donor atoms. Three of the Pb—S bond lengths are are close to each other at 2.7710 (18), 2.8104 (16) and 2.8205 (16) Å, while the fourth Pb—S bond is elongated at 3.0910 (18) Å and reflects the fact that this atom is involved in inter­molecular bridging to an adjacent PbII atom [Pb—S = 3.145 (2) Å]. The bond angles demonstrate that the PbII atom contains a stereochemically active lone pair with a distorted octa­hedral geometry about the PbII atom. This distortion is shown by the S—Pb—S bite angles of 73.63 (4) and 69.50 (4)°, while the remaining S—Pb—S angles range from 81.03 (5) to 143.66 (5)°. One of the benzene rings shows positional disorder over two orientations with occupancy factors of 0.747 (11) and 0.253 (11).
