Crystal structure of [N,N-bis­(di­phenyl­phospho­ro­thio­yl)amidato-κ2S,S′]bis­(tri­phenyl­phosphane-κP)copper(I) di­chloro­methane monosolvate

The title compound, [Cu(C24H20NP2S2)(C18H15P)2]·CH2Cl2 or [Cu(dppaS2)(PPh3)2]·CH2Cl2, is a neutral mononuclear copper(I) complex bearing an N,N-bis­(di­phenyl­phospho­rothio­yl)amidate (dppaS2−) ligand and two tri­phenyl­phosphane ligands. The molecular structure shows that the two S atoms of the dppaS2− ligand [Cu—S = 2.3462 (9) and 2.3484 (9) A] and the two P atoms of the two tri­phenyl­phosphane ligands [Cu—P = 2.3167 (9) and 2.2969 (9) A] coordinate to the copper(I) atom, resulting in a tetra­hedral coordination geometry. The crystallographically observed mol­ecular structure is compared to the results of DFT calculations.
