Abstract
The crystal structure of [tri(o-methoxyphenvl)phosphine]2Cu2Br2 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 frequencies of the complexes of tri(p-tolyl)phos- phine, L3Cu2X2, with cuprous chloride and bromide are consistent with their having halogen-bridged structures with both three- and four-coordinated Cu(I) sites analogous to those formed by triphenyl- phosphine and tri(m-tolyl)phosphine. Cu(I) sites.
