A Fe（Ⅲ） compex with OPPh3,[Fe（OPPh3）4Cl2][FeCl4],has been synthesized and characterized by elemental analysis and IRspectrum.The crystal structure of the title complex has been determined by simgle crystal X-ray diffraction techmiques.The crystal belongs to monoclinic,space group P21/c.The cell parameters are :a=13.9323（13）,b=27.5290（2）,c=18.2095（17）,β= 104.460（2）o,V=6762.9（11）3,Z=4,DC=1.412 g/cm3,μ=0.809 mm-1,F（000）=2952,R1=0.0796 and ωR2=0.1752for 10419 observed reflections（I>2σ（I）） out of 12343 unique data.In the cations[Fe（OPPh3）4Cl2]+,the Fe（Ⅲ） center adopts a slight distoned octahedral geometry comprised oftwo OPPh3 oxygen atoms and two Cl-ions at the equatorial positions,and two OPPh3 oxygenatoms at the axial positions.In the anions[FeCl4]-,The Fe（Ⅲ） ion has a sIightly distortedtetrahedI.al coordination geometry and is bonded to four Cl-ions.
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.
