The synthesis and structure of the two hexafluorophosphate salts {CU[P(C7H7)(3)](CH3CN)(2)}PF6 and {CU[P(C7H7)(3)](2)}PF6 containing the ligand tri(1-cyclohepta-2,4,6-trienyl)phosphane

摘要

The reactions of [Cu(CH3CN)(4)]PF6 (1) with one or two equivalents of tri(1-cyclohepta-2,4,6-trienyl)phosphane lead to {Cu[P(C7H7)(3)](CH3CN)(2)}PF6 (2) and {Cu[P(C7H7)(3)](2)}PF6 (3), respectively. According to the X-ray structure analyses, the cations in both 2 and 3 contain copper(I) in a pseudo-tetrahedral coordination sphere, in which a P(C7H7)(3) ligand provides one or two olefinic bonds for weak interaction with the metal.
