摘要
A new complex [Rh（COD）（2,2＇-bipy）]·[Rh（COD）Cl2]（COD = 1,5-cyclooctadiene, 2,2＇-bipy = 2,2＇-bipyridine） has been synthesized and characterized by elemental analyses, NMR and single-crystal X-ray diffraction. The complex crystallizes in triclinic system, space group P1 with a = 7.4782（14）, b = 10.1400（11）, c = 16.6982（14） , α = 103.494（11）, β = 91.996（13）, γ = 103.829（12）o, C26H32Cl2N2Rh2, Mr = 649.26, V = 1190.0（3）3, Dc = 1.812 g/cm3, Z = 2, F（000） = 652, μ（Mo Kα） = 1.629 mm-1, R = 0.0286 and w R = 0.0463 for 3718 observed reflections（I 2σ（I））. The complex was linked to form 1D chains by hydrogen bonding interaction（C–H···Cl）, and further to construct a 2D layer structure by π···π stacking interactions between the pyridine rings of 2,2＇-bipy ligands. The hydroformylation catalyzed by the title complex was also studied.
