Synthesis and characterisation of diorganotin(IV) complexes of 3,4-dihydroxybenzaldehyde semicarbazone

The diorganotin(IV) complexes of the type Me2SnL, Bu2SnL and Ph2SnL (L) with the anion of the semicarbazone ligand formed by condensation reaction of 3,4-dihydroxybenzaldehyde with semicarbazide were synthesized using 1:1 metal to ligand reactant ratios. The newly synthesized complexes were characte...

Description
Summary:The diorganotin(IV) complexes of the type Me2SnL, Bu2SnL and Ph2SnL (L) with the anion of the semicarbazone ligand formed by condensation reaction of 3,4-dihydroxybenzaldehyde with semicarbazide were synthesized using 1:1 metal to ligand reactant ratios. The newly synthesized complexes were characterized using elemental analysis, infrared and nuclear magnetic resonance (1H, 13C,119Sn) spectroscopic techniques. Complex formation between the organotin(IV) moiety and the anion of 3,4-dihydroxybenzaldehysemicarbazone occurred with chelation at the o-dihydroxy positions. The complexes were proposed to have tetrahedral geometry.
