Treatment of the manganese(tricarbonyl)diphosphine dimers [(CO)3(P-P)Mn]2 (where, P-P is dppe {Ph2P(CH2)2PPh2}, dppp {Ph2P(CH2)3PPh2}, dppb {Ph2P(CH2)4PPh2}, dpppe {Ph2P(CH2)5PPh2}, dtpe {(p-tol)2P(CH2)2P(p-tol)2}, and dcpe {(chex)2P(CH2)2P( chex)2}), with 1-propanol, 1-butanol, 1-pentanol, or 1-hexanol yielded fac-(CO)3(dppe)MnH (1), fac-(CO)3(dppp)MnH (2), fac-(CO)3(dppb)MnH (3), fac-(CO)3(dpppe)MnH (4), fac-(CO)3(dtpe)MnH (5), and fac-(CO)3(dcpe)MnH (6), respectively, and the corresponding aldehydes. Also treatment of Mn2(CO)10 with P-P in 1-propanol, 1-butanol, 1-pentanol, or 1-hexanol yielded the corresponding manganese(I) hydrides (1-6) and aldehydes. Structural characterization of 5 demonstrates a manganese-hydrogen (Mn-H(1)) bond length of 1.57(3) ? which is in close agreement with the manganese-hydrogen bond length of 1.60(2) ? observed in (CO)5MnH by neutron diffraction analysis.

Treatment of the salts fac- (M=Mn, Re; P-P=dppe, dppp) with NaBH4 gives the corresponding formyl complexes, fac-(P-P)M(CO)3CHO in excellent yield.Solutions of these formyls undergo spontaneous loss of CO to give the corresponding hydride
