Trichlorostannatoplatinum(II) complexes containing bis(2-diphenylphosphinoethyl)phenylphosphine, etp, and the tripod ligand tris(2-diphenylphosphinoethyl)phosphine, PP3, respectively, have been prepared and characterized by 119Sn and 31P NMR spectroscopy. (BPh4) (1a) reacts with SnCl2 via oxidative addition to give (BPh4) (1b).The 31P NMR spectral patterns of type 1 complexes are consistent with AX2 spin-systems and square planar structures in solution.There is 31P NMR evidence that in the presence of (Ph4P)Cl 1b adds further SnCl2.The possibility of the formation of (2) is discussed. (BPh4) (3a) reacts with SnCl2 to give (BPh4) (3b).The 31P NMR spectral patterns of 3a and 3b are consistent with AX3 spin-systems and trigonal bipyramidal structures. - Key words: Trichlorostannate, Polyphosphines, Platinum(II), NMR Spectra, Stereochemistry
