Abstract
63,65Cu and 79,81Br spectra of halogenocuprate (I) complexes containing [CuPPh3 X2]- (X = Cl, Br, I) anions with different cations were recorded in the range 77 K -300 K. The results confirm the previous trend that, for a given ligand, 63Cu NQR frequencies are in the order Cl> Br > I. 63Cu NQR frequencies in [CuPPh3 X2]- are compared with those in neutral Cu(Ph3)2 X(X = Cl, Br) complexes and with the [CuX2]- (X = Cl, Br) anions, other three-coordinate Cu(I) complexes.
