Diorganotin(IV) complexes with acetone N(4)-phenylthiosemicarbazone (Haptsc) as ligand. The crystallographic structures of [Sn(CH3)2(aptsc)X] (X=Cl and Br)
摘要:
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 and NMR (H-1, Sn-119) spectroscopic. methods, elemental analysis and X-ray crystal structure determination. The X-ray study revealed that both complexes possess a trigonal bipyramidal geometry. (1) crystallizes in the orthorhombic crystal system, space group P2(1)2(1)2(1), with a = 10.5157(6), b = 12.2085(15), c = 12.496(3) Angstrom, V = 1604.2 Angstrom(3) and Z = 4. (2) crystallizes in the monoclinic crystal system, space group P2(1)/c, with a = 17.3253(17), b = 7.2323(6), c = 13.3527(15) Angstrom, beta = 108.560(10)degrees, V = 1586.1 Angstrom(3) and Z = 4.
