Synthesis and structural studies of some organotin(IV) complexes with macrocyclic ligands

Abstract

186-188Six five-coordinated complexes of diotganotin(IV) with general formula [Ph2SnL]X2 where L = 1,4,8,11-tetraaza tetradeca-5,7,12,14-tetraene or 1,4,8,11-tetradeca 2,3,9,10- dibenzocyclotetradeca-5,7,12,14-tetraene and X = CIO, BF, NO have been prepared and characterized through elemental analysis and molar conductance data. The IR and 1H NMR spectra show that only three out of the four nitrogens of ligand L and the two phenyl groups are coordinated to tin atom leading to trigonal-bipyramidal structure for the complexes
