Complex [Ag 2(DPYBIM)(dppm)](BF 4) 2·CH 3OH was obtained from the reaction of AgBF 4 and the hetero-armed tripodal ligand DPYBIM [N,N-bis(2-pyridylmethyl)-N-(2-benzimidazolylmethyl)amine] with the participation o...Complex [Ag 2(DPYBIM)(dppm)](BF 4) 2·CH 3OH was obtained from the reaction of AgBF 4 and the hetero-armed tripodal ligand DPYBIM [N,N-bis(2-pyridylmethyl)-N-(2-benzimidazolylmethyl)amine] with the participation of dppm [bis(diphenylphosphino)- methane]. Single crystal X-ray diffraction analysis showed that the crystal belongs to the triclinic space group P1-. The cell parameters are: M r=1135.17, a=1.0619(2) nm, b=1.4246(3) nm, c=1.6767(3) nm, α=91.08(3)°, β=104.04(3)°, γ=101.77(3)°, V=2.4027(8) nm 3, D c=1.569 Mg/m 3, Z=2, F(000)=1140, μ=9.53 cm -1, R=0.057, wR=0.145. In the complex, one of the Ag atoms is linearly coordinated by PN from dppm and the benzimidazolyl group of the tripodal ligand, respectively, while the other is tetrahedrally coordinated by PN 3 where two of the N atoms are from the pyridine arms and one is the amino-N. Two types of intermolecular π...π interactions lead to the 1D infinite "Z"-shaped chain. The complex was characterized by elemental analysis, IR and MS. 31P NMR showed characteristic AA′XX′pattern of two symmetrical multiplets centered at δ=10.07.展开更多

The compound has been characterized by element analysis, IR, 1H NMR, MS spectfa and a single crystal X-ray structure determination.Its structure consists, of a distorted tetrthedral core FeCo2S in which the Co（1）, Co（2）, Fe, and S atoms occupy a vertex of the tetrahedron respectively, and the P atoms of O [P（SCH2）2]2 bonded to two Co atoms in their axial positions.展开更多
