Abstract
The structural transitions in (C4H9NH3)(2)SnCl6 and (C4H9NH3)(2)SnCl6 have been studied by proton NMR spectroscopy. The temperature dependences of the proton magnetic resonance absorption spectra have been determined and also those of the second moment (M-2). For the former compound, the phase trans ition was found to be connected with the motions of SnCl62- octahedra disto rtion. NH3 group reorientation and diffusion of chain defects dominate the nuclear resonance relaxation results in the latter compound.
