Abstract

AbstractA series of organotin(IV) complexes with 2‐mercapto‐5‐methyl‐1,3,4‐thiadiazole (HL) of the type R3 Sn(L) (R = Me 1; Bu 2; Ph 3; PhCH2 4) and R2Sn(L)2 (R = CH3 5; Ph 6; PhCH2 7; Bu 8) have been synthesized. All complexes 1–8 were characterized by elemental analysis, IR,1H, 13 C, and 119Sn NMR spectra. Among these, complexes 1, 3, 4, and 7 were also determined by X‐ray crystallography. The tin atoms of complexes 1, 3, and 4 are all penta‐coordinated and the geometries at tin atoms of complexes 3 and 4 are distorted trigonal–bipyramidal. Interestingly, complex 1 has formed a 1D polymeric chain through Sn and N intermolecular interactions. The tin atom of complex 7 is hexa‐coordinated and its geometry is distorted octahedral. © 2006 Wiley Periodicals, Inc.
