The structural transitions in (C 4 H 9 NH 3 ) 2 SnCl 6 and (C 4 H 9 NH 3 ) 2 SnCl 6 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 transition was found to be connected with the motions of SnCl 2— 6 octahedra distortion. NH 3 group reorientation and diffusion of chain defects dominate the nuclear resonance relaxation results in the latter compound.
