双二苯基膦甲烷和μ^4-S的四核铜(Ⅰ)配合物的 合成与结构

室温下，双核配合物Cu(dppm)(NO~3)]~2与二硫化碳反应制备了四核铜(Ⅰ)配合物Cu~4(S)(dppm)~4](PF~6)~2·CH~2Cl~2(dppm=双二苯基膦甲烷)，并经光谱学方法表征了配合物的物理化学性质。X射线四圆衍射测定结果表明dppm属桥式双齿配位，S^2^-以μ^4形式与中心铜离子配位，PF~6^-位于配合物的外界，铜离子呈现三角平面配位构型。

Synthesis and Structure of Tetranuclear μ4-S Copper(Ⅱ) Complex with Bis(diphenylphosphino)methane

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)]~2dppm=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.
