摘　　要：Tetranuclear Cu(I)complex,Cu4(imdt)(NO3)4.6H2O(imdt=1,3-imidazolidine-2-thione),was synthesized by areaction of Cu(NO3)2with imdt in water.It crystallizes in monoclinic crystal system,space group C2/c(No.15),with a =3.1418(3)nm,b =0.94332(6) nm,c =2.3027(2) nm,β=119.773(3)°,V =5.9236(9) nm3,Z =4,Mr=1529.68.mol-1,Dc.=1.715g.cm-3,μ=1.815 mm-1,F(000) =3144,R1=0.028,wR2=0.065.The crystal structure consists of tetranuclear[Cu4(imdt)9]4 +cation,in which Cu(I)is coordinated with four S atoms from four imdt ligands to form a distorted tetrahedral geometryand imdt ligands exhibit three coordination modes of terminal monodentate S-donating andμ2—S andμ4—S bridging coordina-tion.Tetranuclear Cu （ Ⅰ ） complex, Cu, （imdt） （ NO3 ） 4 · 6H2 O （ imdt = 1,3 - imidazolidine - 2 - thione ）, was synthesized by a reaction of Cu（ NO3 ）2with imdt in water, it crystallizes in monoclinic crystal system, space group C2/e （No. 15 ）, with a = 3. 1418 （3）nm,b =0.94332（6） nm,e = 2.3027（2） nm,β= 119.773（3）°,V = 5.9236（9） nm^3,Z =4,Mr = 1529.68. mol^-1,Dc. = 1. 715g · cm^-3 ,μ = 1. 815 mm^-1 ,F（000） = 3144, R1 = 0. 028 ,wR2=0. 065. The crystal structure consists of tetranuelear[Cu4 （imdt）9]^4＋. cation,in which Cu（Ⅰ） is coordinated with four S atoms from four imdt ligands to form a distorted tetrahedral geometry and imdt ligands exhibit three coordination modes of terminal monodentate S - donating and μ2-S and μ4-S bridging coordination.
