| NMR and Dilatometric Studies on [N(CH 3 ) 4 1 3 M 2 X 9 (M = Sb, Bi; X = C1, Br)  | | | Abstract
| Thermal expansion studies on [N(CH 3) 4 ] 3 Sb-,Cl 9 and [N(CH 3) 4 ] 3 Sb 2 Br 9 are reported. The relax-ation times 'H T, were measured for [N(CH 3) 4 ] 3 Bi 2 Cl 9 , [N(CH 3) 4 ] 3 Sb 2 Br 9 , and [N(CH 3) 4 ] 3 Bi 2 Br 9 in the temperature range 100-290 K. To interpret the 7\ data on [N(CH 3) 4 ] 3 Bi 2 Cl 9 the method of Tj calculation reported by Takeda et al. has been applied successfully. Two different, inequivalent types of [N(CH 3) 4 ] 3 cations for all tetramethylammonium crystals are found. | | |
