THE NQR AND STRUCTURE OF HEXABROMOANTIMONATE(III) AND BISMUTHATE(III) IONS
79Br NQR spectra were observed in (R2NH2)3MBr6 (R=C2H5, n-C3H7;M=Sb, Bi). Widely spaced resonance lines and their unusual temperature dependence were found in the diethylammonium salts. These findings are accounted for in terms of the crystal structure determined by means of X-ray diffraction.
