【摘要】 室温下,双核配合物[Cu（dppm）（NO₃）]₂与二硫化碳反应制备了四核铜（Ⅰ）配合物[Cu₄（S）（dppm）₄]（PF₆）₂CH₂Cl₂（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μ⁴形式与中心铜离子配位,PF₆^-位于配合物的外界,铜离子呈现三角平面配位构型.更多还原

【Abstract】 Tetranuclear μ4 - S copper( I ) complex [ Cu4(S) (dppm)4] (PF6)2· CH2C12 was obtained by reaction of [Cu(dppm) (NO3)]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 μ4 - S Cu ( I ) atoms in a tetranuclear copper( I ) complex, and PF6- was the counter ion in the formation of tetranuclear copper( I ) complex. The copper( I ) ions have a trigonal planar geometry with a P2S donor set. The crystalline data are: C101H90 Cl2Cu4F12P10S, Mr = 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. 234nm3, Dc = 1. 427g cm-3, Z = 4, F(000)=4480, u(MoKa)=11.16(cm-1), R =0.078.更多还原
