Synthesis and Crystal Structure of Bis(μ-bis(diphenyl-phosphino)methane)(μ-benzenethiolate)(acetonitrile)Dicopper(I) Perchlorate Diethylether Solvate

The reaction between [Cu2(μ-dppm)2(MeCN)4](ClO4)2(dppm=bis(diphenylphos-phino)methane) and [Zn(PhS)2(bpy)] (bpy=2,2'-bipyridine,PhS=benzenethiolate) gave the complex [Cu2(μ-dppm)2(μ-PhS)(MeCN)]ClO4·0.5(Et2O)(C58H52ClNO4P4SCu2·0.5Et2O) which was determined by X-ray single-crystal diffraction.The crystal is of orthorhombic,space group P212121 with a=13.6157(3),b=20.8022(6),c=21.3299(6)A,V=6041.4(3) A3,Mr=1182.54,Dc=1.300 g/cm3,F(000)=2444,μ=0.934 mm-1 and Z=4.The final R=0.0773 and wR=0.1843 for 7744 observed reflections (I>2σ(I)).The dicopper atoms are doubly bridged by dppm as well as one S donor from benzenethiolate.One copper atom is in a distorted trigonal bipyramidal environ- ment,whereas the other adopts a distorted tetrahedral geometry.     

Synthesis and Crystal Structure of a Tetranuclear Silver Complex with Bis（diphenylphosphino） amine-dioxide as a Tridentate Ligand

1 INTRODUCTION The coordination chemistry of the nitrogen-contai- ning diphosphine ligand bis(diphenylphosphino)ami- ne (Ph2PNHPPh2) has recently received much atten- tion because the P atoms can bridge metal centers in μ-bonding mode to form bi- or polynuclear complex- es[1~10]. It has been shown that the acidity of N–H proton would promote functionalization on the ligand backbone[4, 5, 11]. Although a few complexes contain- ing deprotonated tridentate Ph2PNPPh2 have been synthesi…

Synthesis and Crystal Structure of Bis（p—aminotoluene）—bis（dimethylglyoximato） Cobalt（Ⅲ） Perchlorate

The title compound (C22H32.5ClCoN6O8.25,Mr=607.42)crystallizes in the orthorhombic system,space group c222 1 with a=11.320(2),b=20.933(4),c=23.936(5)A,V=5672(2)A^3,Dc=1.423g/cm^3,Z=8,μ(MoKα）=0.754mm^-1,F(000)=2532,R=0.0512 and wR=0.1190,There are eight complex molecules [Co(C4H6N2O2)(C4H8N2O2)(C7H9N)2]ClO4.0.25H2O of C2 crystallographic symmetry in a unit cell,including two crystallographically independent molecules,in which different orientations of the MePhNH2 groups are found.Two MephNH2 groups are in trans position for molecule A,and cis for B.The central metal atom is in a distroted octahedral environment.The hydrogen bonds of O-H(oxime)…O and N-H(p-aminotoluene group)…O construct an one-dimensional chain along the c axis in the title compound.     

Synthesis and Crystal Structure of a Novel Polymeric Complex [WS4Cu4（PY）4（μ-CN）2]∞

1 INTRODUCTION The synthesis of Mo(W)/Cu(Ag,Tl)/S polymeric complexes from the reactions of [MS4]2- (M = Mo, W) with Cu , Ag or Tl remains attractive due to their rich coordination chemistry[1～10] and NLO ma- terials[7, 10]. For example, the reacti…
