Abstract
Diorganotin(IV) diperchlorate complexes of heterocyclic ligands of the composition (R2SnLn)(ClO4)2 with L = pyridine, quinoline, 2,2'-bipyri dine and 1,10-phenanthroline, have been Prepared and characterized by molar conductance measurements and IR, H-1 NMR and Sn-119 Mossbauer sp ectroscopic studies. The complexes with two monodentate ligands are re ported as tetrahedral while the complexes with four monodentate or two -bidentate ligands as distorted octahedral structures where the R2Sn g roup occupying a trans-position. Distortion of the C-Sn-C bond angle f rom linearity has been calculated. Its value lies between 146-162-degr ees (R = methyl) and 145-degrees (R = phenyl).
