A SIMPLE SYNTHESIS AND CRYSTAL-STRUCTURE OF THE DINUCLEAR DIPHOSPHIDO-BRIDGED PALLADIUM(I) COMPLEX [PD(P(TERT-BU)2H)(MU-P(TERT-BU)2)]2

UV irradiation of Pd(P(t)Bu3)2 in n-hexane or THF gives the diamagnetic dinuclear complex [Pd(P(t)Bu2H)(mu-P(t)Bu2)]2, 2-methylpropene, and hydrogen. The complex was also obtained from the reaction of Pd(eta(5)-C5H5)(eta(3)-C3H5) with P(t)Bu2H in toluene. Its crystal and molecular structure were determined by an X-ray diffraction study. Each Pd bears a terminal P(t)Bu2H ligand and the two metal centers are bridged by two phosphido ligands.
