TRIS(N,N-DIETHYLDITHIOCARBAMATO-S,S')PHENYLTIN

The title structure, [Sn(C5H10NS2)(3)(C6H5)], consists of monomeric mo lecular chelate complexes in which the Sn atom has distorted pentagona l bipyramidal coordination with five S atoms in equatorial sites. One of the dithiocarbamate ligands has a short [2.570 (2) Angstrom] and a long [2.766 (2) Angstrom] Sn-S distance, a second dithiocarbamate liga nd has almost equal Sn-S distances [2.676 (2) and 2.602 (2) Angstrom] and the axial-equatorial dithiocarbamate ligand has a long equatorial Sn-S distance [2.757 (2) Angstrom] and a short axial Sn-S distance [2. 458 (2) Angstrom]. The axial Sn-C distance is 2.113 (3) Angstrom. Dist ortion from the idealized pentagonal bipyramid has been attributed to the steric requirements of the four-membered MS(2)C ring and to the li mited bite angle of the dithiocarbamate ligand.
