Diorganotin(IV) complexes with acetone N(4)-phenylthiosemicarbazone (Haptsc) as ligand. The crystallographic structures of [Sn(CH3)2(aptsc)X] (X ¼ Cl and Br)

The reaction of Haptsc with SnMe2Cl2 and SnMe2Br2 yielded [Sn(CH3)2(aptsc)Cl] (1) and [Sn(CH3)2(aptsc)Br] (2), respectively. The complexes were characterized by IR andNMR(1H, 119Sn) spectroscopic methods, elemental analysis and X-ray crystal structure determination. The X-ray study revealed that both complexes possess a trigonal bipyramidal geometry.
