Cu-63, Cu-65 and Br-79, Br-81 spectra of halogenocuprate (1) complexes
containing [CuPPh3X2]- (X = Cl, Br, I) anions with different cations
were recorded in the range 77 K - 300 K. The results confirm the previ
ous trend that, for a given ligand Cu-63 NQR frequencies are in the or
der Cl > Br > 1. Cu-63 NQR frequencies in [CuPPh3X2]- are compared wit
h those in neutral Cu (Ph3)2X(X = Cl, Br) complexes and with the [CuX2
]- (X = Cl, Br) anions. Br-81 frequencies are compared with those of o
ther three-coordinate Cu(I) complexes.
