Bis[O,O′-bis(4-tert-butylphenyl) dithiophosphato-κ2S,S′]bis(pyridine-κN)lead(II)

Abstract

In the title compound, [Pb(C20H26O2PS2)2(C5H5N)2], the PbII ion is coordinated by two S,S′-bidentate anions and two pyridine molecules. The PbN2S4 coordination geometry approximates to a pentagonal bipyramid with one equatorial site vacant. The N atoms occupy the axial sites. One of the pyridine molecules is disordered over two sets of sites in a 0.907 (7):0.093 (7) ratio and one of the tert-butyl groups is disordered over two sets of sites in a 0.534 (6):0.466 (6) ratio. An intramolecular C—H...O interaction occurs in one of the ligands. In the crystal, pairs of short Pb...S contacts [3.4018 (11) Å] generate a centrosymmetric dimeric assembly with the distant S atom lying in the region of the vacant coordination site of the metal atom. No directional packing interactions occur.
