A series of hydride-bridged dipalladium complexes supported by bis(diphenylphosphino) methane (dppm) ligands has been prepared. The complexes [Pd2R2 (μ-H) (μ-dppm)2]PF6 (R = Me, Et, Bu, CH2SiMe3, Ph) were generated by reduction, using NaBH3CN, of the corresponding halide-bridged species. The products are thermally stable, yellow solids, and they have been characterized by 1H and 31P{1H} NMR spectroscopy. The ethyl complex [Pd2Et2(μ-H) (μ-dppm)2]PF6 has been characterized further by X-ray crystallography. It crystallizes in the monoclinic space group P21/c with a = 10.6160 (1), b = 12.8637 (1), c = 25.3739 (3) A?, β = 97.479 (1)° and Z = 2. The cation adopts an A-frame structure, with a Pd-Pd distance of 2.9933 (7) A?.
