Spectral Area

The temperature dependence in the 119Sn Mössbauer spectral area for {(CH3)2NH2}2SnCl6 was found to be almost linear, although a phase transition of the complex has been suggested by IR, 35Cl NQR and NMRstudies, while an anomaly in the temperature dependence for {(CH3)2NH2}2SnBr6 was found at 235 K, which is close to the phase transition temperature 253 K determined by 89Br NQR. These differences are attributable to molecular motion of the dimethylammonium ion in the complexes. The X-ray powder diffraction pattern of {(CH3)2NH2}2SnCl6 did not change near the phase transition point, but that of {(CH3)2NH2}2SnBr6 changed at 108 - 123 K and 233 - 253 K
