The mononuclear copper(I) complex, [Cu(dppe)2](PF6)(CH3COCH3) [dppe = bis-(diphenylphosphino)ethane] has been synthesized and characterized by X-ray crystallography. The crystal belongs to monoclinic, Mr=1062.3, space group P21/n with cell parameters a =14.741(2), b =19.354(8), c =18.587(3) A, β = 91.41(1)°, V = 5301.5 A3, Z = 4, Dc=1.302 g/cm3, F(000)= 2200, μ = 6.16cm-1, R=0.062, Rw = 0.068. A total of 9679 independent reflections were collected, of which 4574 reflections with I >3σ(I) were observed. The central Cu atom is coordinated by four P atoms from dppe to form a distorted tetrahedral environment. In the coordination sphere the bond lengths of Cu-P(1), Cu-P(2), Cu-P(3) and Cu-P(4) are 2.298(2), 2.305(2), 2.311(2) and 2.295?, respectively; and the P-Cu-P bond angles vary from 87.52(9) to 120.12(9)°.
