Abstract
The crystal structures of the condensed bromocadmate anions with chains built of [CdBr3] were determined by X-ray structure analysis at 300 K. In addition, the temperature dependence of the ‘1Br NQR frequencies was observed. [(t-C4H9NH3)CdBr3]2-H2O(1) crystallizes with a double Br bridged chain (monoclinic, P2/c, Z = 4, a= 1963.4(8), b = 887.7(4), c= 1432.1(6) pm, and β= 110.66(2)°). Six Br NQR lines are observed at temperatures between 77 and 330 K. (j-C3H7NH3)CdBr3(2) crystallizes with a triple Br bridged chain (orthrhombic, Pbca, Z= 8, a = 1975.4(6), b = 1415.8(4), c = 690.1(2) pm). (2) shows three 81Br NQR lines at temperatures between 77 and 193 K. A phase transition occurs at 224 K. The structure of [(CH3)3NH]3Cd2Br7] (3) was redetermined. (3) consists of a triple Br bridged chain and a discrete [CdBr4] tetrahedron (hexagonal, P63mc, Z= 8, a = 1483.5(2), c = 685.7(5) pm). The structure of (3) is identical to the one reported by Daoud, Perret, and Dusausoy, Acta Crystallogr., B35, 2718 (1979). Three 81Br NQR lines are observed at temperatures between 77 and 243 K.
