“…1, with organotin halides in aqueous media using vibrational and NMR ( 1 H, 13 C, 15 N, 31 P and 117,119 Sn NMR, using, where appropriate, one-and two-dimensional techniques) spectroscopies (see, for example Ghys et al, 6 Jancso et al, 7 Yang et al 8 and Nafisi et al 9 ), as well as stability constant studies, 10,11 has revealed that this is not the case. Solid-state studies of isolated complexes, using NMR, 6 Mössbauer, 8 -16 and IR spectroscopies, and frozen solutions, using Mössbauer spectroscopy, similarly confirm this.…”
