摘要：

Two ionic triphenyltin complexes (1 and 2) were obtained via condensation of triphenyltin hydroxide with oxalic and malonic acids in the presence of di-isobutylamine. Their structures have been characterized by IR and multinuclear (H-1, C-13, and Sn-119) NMR spectroscopies. The coordinations of tin in the two triphenyltin complexes are confirmed by X-ray crystallographic studies. In the solid state, oxalate complex 1 consists of a di-isobutylammonium cation and an oxalatotriphenylstannate anion. Tin is five-coordinate with a cis-trigonal-bipyramid (TBP) geometry, as the oxalate is a chelating bidentate ligand. Complex 1 is a 1-D polymer via hydrogen bonding between carboxylate oxygen and ammonium nitrogen. The crystallographic studies reveal that 2 is a trinuclear triphenyltin complex formed with the molar ratio of tin, acid, and amine being 3:2:1. A negative charge is delocalized among the three tins in the complex; all tins have trans-TBP geometry with three phenyls in the equatorial plane and two O in axial positions. The malonates in 2 are bridging tridentate with the free carbonyl hydrogen bonded to di-isobutylammonium through an ethanol. This coordination and significant inter- and intramolecular hydrogen bonds between ammonium and malonate result in a 3-D polymeric structure for 2.
