Triphenylphosphane complexes of copper(I): Structural and 31P NMR investigations

Article abstract of DOI:10.1016/0277-5387(95)00595-1

The phosphane complexes [(Ph₃P)₂CuCl₂Li(THF)₂] · 1.5THF, [(Ph₃P)₂CuCl] · 0.5THF, [(Ph₃P)₃CuCl] · MeCN, [(Ph₃P)₃CuCl] · THF and [(Ph₃P)₂CuCl₂Cu(PPh₃)] (THF = tetrahydrofuran) have been prepared and characterized on the basis of analytical, IR, mass and NMR spectral techniques. The crystal structures of the complexes underline the ability of the copper(I) centre to exist in a distorted trigonal planar as well as in a distorted tetrahedral environment. Copyright
