In the title compound three bidentate 2-pyridinethiolato ligands (2-SP
y) together with p-tolyl form a distorted pentagonal bipyramid around
Sn. Two S atoms and three N atoms form the pentagonal plane. One S and
the C(p-tolyl) atom are in the axial positions. The distortion of the
molecule is explicated by the axial S-Sn-C angle of 156.0 (3)-degrees
and by the distance of 0.635 (7) angstrom of one of the N atoms from
the pentagonal plane. The Sn-S distances in the plane are longer [2.57
1 (3) angstrom] than the axial Sn-S bond [2.486 (3) angstrom]. The Sn-
N distances are in the range 2.468 (8) +/- 0.024 angstrom. Intermolecu
lar distances shorter than the sum of the van der Waals radii do not e
xist.
