In the title compound, [Pb(C14H14O2PS2)2] n , the metal atom is surrounded by two O,O'-bis-(2-methyl-phen-yl) dithio-phosphate 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 inter-molecular bridging to an adjacent Pb(II) atom [Pb-S = 3.145 (2) Å]. The bond angles demonstrate that the Pb(II) atom contains a stereochemically active lone pair with a distorted octa-hedral geometry about the Pb(II) 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).
