 Abstract    63-65Cu and 79,81Br spectra of halogenocuprate (I) complexes containing [CuPPh3 X2]~ (X = C1, Br, I) anions with different cations were recorded in the range 77 K -3 0 0 K. The results confirm the previous trend that, for a given ligand, 63Cu NQR frequencies are in the order C l> B r > I. fe3Cu NQR frequencies in [CuPPh3 X2]_ are compared with those in neutral Cu(Ph3)2 X(X = Cl, Br) complexes and with the [CuX2] (X = C1, Br) anions, other three-coordinate Cu(I) complexes.

 Title    Crystal Structure and NQR of Two Copper (I) Complexes of 4,6-Dimethylpyrimidine-2-thione  
 Abstract    The crystal structure and 63Cu NQR spectra of two neutral hexanuclear Cu(I) complexes of 4,6-dimethylpyrimidine-2-thione, (Hdmpt); [dmptCu]6 6 CHCl3 (l) and [dmptCu]6 C2 H4 Cl2 (2), are reported. The number and relative intensities of the NQR resonances are in agreement with the results of the crystallographic study. The temperature-dependence of the resonances reveals that both compounds undergo a phase-change in the temperature range 77 K -3 0 0 K, both of which may be associated with the loss of a symmetry-element present in the high-temperature phase. The 3 5 C1 resonances of CHC13 in 1 could be observed in the low-temperature phase but the corresponding resonances for C2 H4 C12 in 2 were not detected.
