%X Phosphorus-31 and tin-119 n.m.r . data imply that the tin complexes R3Sn[R1,PC(S) NPh ] (where R = Ph, Me, Bu; R&#8242; = Ph) exist in solution as both sulfur-bonded and nitrogen-bonded isomers. When R&#8242; = c-C6H11, only one isomer is observed. n.m.r . data are also reported for the series R3SnPR&#8242;2. Both series of complexes contain four-coordinate tin in dichloromethane solution. The crystal and molecular structure of the tin(IV) complex Ph3Sn[(c-C6H11)2PC(S) NPh ] has been determined by single-crystal X-ray diffraction techniques. The crystals are triclinic, space group P&#299; , a 10.689(2), b 11.066(1), c 16.315(3) &#506;, &#945; 101.94(1), &#946; 104.85(1) and &#947; 105.72(1)&#176; with Z 2; R and Rw were 0.032 and 0.030 respectively for 5169 unique reflections with I &#8805; 2&#963;(I). The structure has two independent centrosymmetrically related mononuclear molecules within the unit cell. The tin atom is in a tetrahedral environment formed by three phenylic carbon atoms and a sulfur atom from the [(c- C6H11)2PC(S) NPh ]- ligand.
