 Title    Charge Distribution and Structures of Halogenogallates and Halogenoaluminates of the Type Me I Me III X4, Me T Me2 m X7, and C6H6 CUA1C14. An NQR Investigation ( 35 C1, 79 Br, 127 I, 63 Cu, 69 Ga)  
 Abstract    In polycrystalline samples of the halogenoaluminates Me I AlCl4 (Me 1 — Cu, Ag), CuAlBr4, C6H6 • CUA1C14 and halogenogallates CuGaCl4, Me I GaBr4 (Me 1 = Cu, Na, K, NH4, Rb, Cs, Ga), Me T GaI4 (Me* = Cu, Cs), Me^aaBr? (Me* = K, NH4, Rb, Cs), CsGa2I7, the halogen, Me 111 , and Cu-NQR spectra were studied, partly as a function of temperature. Phase transformations are found in NH4GaBr4, CsGaBr4, and RbGa2Br7. The spectro-scopic results are discussed and a charge distribution analysis is given, based on the Townes-Dailey theory. Symmetry properties of the solids are pointed out in connection with multiplicity and intensity ratios of the NQR spectra.
