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) Å] and the two P atoms of the two triphenylphosphane ligands [Cu - P = 2.3167 (9) and 2.2969 (9) Å] 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.
