N2 - The X-ray powder diffraction patterns for tetramethylammonium bromide and iodide have been measured from near room temperature up to decomposition/sublimation. The unit cell parameters were refined and the coefficients of thermal expansion calculated. Unlike N(CH3)4Cl [M. Stammler, J. Inorg. Nucl. Chem. 29, 2203-2221 (1967)], N(CH3)4Br (1Br) and N(CH3)4I (1I) undergo no solid-solid transitions before decomposition/sublimation as was observed earlier by thermal analysis [S. S. Chang and E. F. Westrum, J. Chem. Phys. 36(9), 2420-2423 (1962); Coulter et al., J. Am. Chem. Soc. 62, 2845-2851 (1940); Xenopoulos et al., Mol. Cryst. Liq. Cryst. 214, 63-79 (1992)].
