Tetranuclear μ^4-S copper(Ⅰ) complex [Cu~4(S)(dppm)~4](PF~6)~2· CH~2Cl~2 was obtained by reaction of [Cu(dppm)(NO~3)]~2[dppm=bis (diphenylphosphino) methane] with carbon disulfide. The title complex was characterized by IR, XPS, ^1H NMR and emission spectroscopy. X- ray data showed that the dppm coordinates served as a bidentate bridging ligand to the μ^4-S Cu(Ⅰ) atoms in a tetranuclear copper(Ⅰ ) complex, and PF~6^- was the counter ion in the formation of tetranuclear copper(Ⅰ) complex. The copper(Ⅰ) ions have a trigonal planar geometry with a P~2S donor set. The crystalline data are: C~1~0~1H~9~0·Cl~2Cu~4F~1~2P~1~0S, M~r=2198.69, monoclinic, space group C2/c, a=2.847(1) nm, b=1.6164(3) nm, c=2.424(2) nm, β=113.42(4) °, V=10.234nm^3, D~c=1.427 g·cm^-^3, Z=4, F(000)=4480, μ(MoK~α)=11. 16(cm^-^1), R=0.078.
