摘要：

The 1-pyrrolecarbodithioate complexes of tin, PhSnCl(S2CNC4H4)2. (1) and Sn(S2CNC4H4)4 (2) have been synthesized and characterized by IR and NMR spectra (H-1, C-13 and Sn-119). delta-Sn-119 suggests hexacoordination for 1 and an even higher coordination number for 2. X-ray structure determinations of these as well as of Me2Sn(S2CNC4H4)2 (3) have shown that 3 is one of the few known examples with a skew-trapezoidal bipyramidal configuration. 1 attains approximately a cis-octahedral geometry with two bidentate carbodithioate ligands with the Cl atom and the phenyl group in cis position. Complex 2 possesses two bidentate ligands while the other two are essentially anisobidentate leading to a structure between an octahedraon and a dodecahedron.
