摘要: The dinuclear osmium polyhydride [Os(2)H(7)(PPh(i)Pr(2))(4)][HC(SO(2)CF(3))(2)] (1) was synthesized by the protonation of [OsH(6)(PPh(i)Pr(2))(2)] with bis(trifluoromethylsulfonyl)methane. Treatment amine bases not able to deprotonate 1, but reaction potassium hydride gave corresponding neutral [Os(2)H(6)(PPh(i)Pr(2))(4)] (2). Single crystal X-ray diffraction revealed that 1 and 2 both crystallize in P2(1)/c space group are classical polyhydrides containing similar Os(mu-H)(3)Os cores Os-Os distances 2.5431(1) A 2.5448(2) A, respectively. These structures represent rare examples six or more ligands.
