Abstract
AbstractThe 1‐pyrrolecarbodithioate complexes of tin, PhSnCl(S2CNC4H4)2 (1) and Sn(S2CNC4H4)4 (2) have been synthesized and characterized by IR and NMR spectra (1H, 13C and 119Sn). δ119Sn 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.
