The title complex Cd(dppf)Br2 (dppf=1,1′-bis(diphenylphosphino)ferrocene) (C34H28Br2 P2CdFe, Mr=826.57) has been synthesized and characterized by X-ray diffraction. The crystal is in monoclinic, space group C2/c with cell parameters: a = 34.285(4), b = 10.050(1), c = 18.697(2) ? β= 98.843(3)? V = 6366(1)3, Z = 8, Dc = 1.725g/cm3, (MoKa) = 0.71073 ? =3.757mm-1, F(000)=3248. The final refinement with 4469 observed reflections and 361 parameters gave R=0.0584 and wR=0.1522. The 1,1′-bis(diphenylphosphino)ferrocene group is connected to the Cd atom as a bidentate ligand. The Cd atom has a distorted tetrahedral coordination.
