The 63Cu NQR spectra of five three-coordinated complexes of Cu(I) containing an isocyanide ligand are reported. The resonance frequencies are compared with those of other three-coordinated Cu(I) complexes using a partial coupling constant model to de

The crystal structure of [tri(o-methoxyphenvl)phosphine]2 Cu2Br2 shows it to be a halogen-bridged dimer with three-coordinated Cu (I) sites. The 63Cu NQR frequency of the corresponding chloride indicates that it has a similar structure. The 63Cu NQR
