Abstract: A new diphosphine ligand, 2, 6-bis(diphenylphosphinoethyl) bromobenzene, was synthesized and two new complexes, [PdBr{(Ph₂PCH₂CH₂)₂C₆H₃}] (1) and [PtBr{(Ph₂PCH₂CH₂)₂C₆H₃}] (2), were obtained by the oxidative addition reaction of Pd⁰(DBA)₂(DBAis PhHC = CHCOCH = CHPh) and Pt⁰(PPh₃)₄ with this ligand, respectively.The two complexes were characterized by ³¹P NMR, ¹H NMR and X-ray diffraction.The crystallographic data of complex (1) are: space group Pna2₁, a = 16.806(2)Å, b = 18.578 (2)Å, c = 9.643 (5)Å and these of complex (2) are: space group P2₁/a, a = 12.364(3)Å, b = 17.676(4)Å, c = 13.672(7)Å, β=94.8b(3)°.
