Two-Coordinate Tribenzylphosphine (PBz3) Complexes of Copper(I): Solid State 31P NMR Studies and the Crystal Structure of [Cu(PBz3)2]PF6

Abstract

The structure of [Cu(PBz3)2]PF6 shows it to contain discrete [Cu(PBz3)2]+ cations with a “P2” donor set creating a linear two-coordinate environment for the copper(I) atom. Structural and solid-state 31P NMR parameters for [Cu(PBz3)2]PF6 and the related two-coordinate complex, [Cu(PBz3)2][CuBr2], are compared to those obtained for other three- and four-coordinate copper(I) complexes.
