| Abstract: | Within this study, coordination properties of the cyclic diphosphine 1,2,3,4-tetrahydro-1,4-diphenyl-1,4-benzodiphosphinine (bedip) are investigated, through the preparation of neutral and cationic Pt(II), Pt(IV) and Pd(II) complexes. The diphosphine acts as bridging ligand in the neutral Pt(II) and Pd(II) complexes, affording MX(CH3)(μ-bedip)]2 (X = Cl, Br, I, CH3) species. Chelation is observed in all the remaining complexes. The molecular structures of PtX(CH3)(μ-bedip)]2 (X = Br, I) and PtI(CH3)3(bedip)] are also determined. |
