Bis[O,O'-bis-(4-tert-butyl-phen-yl) di-thio-phosphato-?(2) S,S']bis-(pyridine-?N)lead(II).

ABSTRACT: In the title compound, [Pb(C20H26O2PS2)2(C5H5N)2], the Pb(II) ion is coordinated by two S,S'-bidentate anions and two pyridine mol-ecules. The PbN2S4 coordination geometry approximates to a penta-gonal bipyramid with one equatorial site vacant. The N atoms occupy the axial sites. One of the pyridine mol-ecules 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 intra-molecular C-H?O inter-action 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 inter-actions occur.
