A novel dihydridoruthenate, [(solv)Na][Cp*-((Pr2MeP)-Pr-i)RuH2] (2; solv = THF or OEt2), was synthesized from Cp*((Pr2MeP)-Pr-i)RuCl (1) and sodium triethylborohydride. Compound 2 was used to generate Cp*((Pr2MeP)-Pr-i)RuH equivalents by salt metathesis with 1, which resonance Raman spectroscopy indicates is a mixture of the terminal dinitrogen complex, Cp*((Pr2MeP)-Pr-i)RuH(N-2) (4), and diastereomers of the bridging dinitrogen complex [Cp*((Pr2MeP)-Pr-i)RuH](2)(mu-N-2) (meso, 5, and a pair of enantiomers, 6). Compound 2 also reacted with the late transition metal chloride complexes [(COD)IrCl](2) and (IPr)CuCl [IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene] to form hydride-bridged heterobimetallic complexes Cp*((Pr2MeP)-Pr-i)Ru(mu-H)(2)Ir(COD) (7) and Cp*((Pr2MeP)-Pr-i)Ru(mu-H)(2)Cu(IPr) (8), respectively, that feature weakened Ru-H interactions relative to those of 2.
