The complex containing ferroceneyl, Cd(dppf)I2(dppf=1,1 bis(diphenylphosphino) ferrocene), was synthesized and characterized by IR, Uv vis DRIS spectrum and X ray diffraction. The crystal belongs to monoclinic, space group C2/c, a=37.439(3)?, b=10.2472(6)?, c=18.719(1)?, β=110.4715(16)°, V=6727.8(8)?3, Z=8, Dc=1.818g·cm-3, F(000)=3536, μ=3.015mm-1, R=0.0308, wR=0.0692. dppf coordinates to Cd? as bidentate ligand, and the coordination environment of Cd? is a distorted tetrahedron. The electronic structures of Cd(dppf)I2 and Cd(dppf)Br2 are discussed by quantum chemistry calculation.
