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 octahedral cluster complex Rh 2Co 2(CO) 10(μ 4, η2 -HC≡CFc) 1 reacts with PPh 3 to give the title cluster Rh 2Co 2(CO) 10-n(μ 4, η2-HC≡CFc)(PPh 3) n(2, n=1; 3, n=2, ).

The structure of 3 has been determined by X-ray diffraction. At 60 ℃ and 1.8 MPa of initial total CO/H 2 (1∶1) pressure, the catalytic activity of 3 for hydroformylation of s tyrene has also been investigated. The conversion of the styrene is 98.1%, the selectivity of the aldehydes is 99%, the 3-phenylpropyl aldehyde(n)/2-phenylpropyl aldehyde( i) mole ratio of aldehyde to 1/17.4.展开更多
