Abstract:	Hydrogenation (20 atm, 80°C, 2 h) of trinuclear Ru₃(CO)_12-nL_n (L= tertiary phosphine or phosphite; n = 1–3) resulted in aggregation to give mixtures of H₄Ru₄(CO)12-n(L)_n (n = 0–4), but Ru₃(CO)₁₀(L-L) (L-L=dppm, dpam) gave Ru₃(μ-H)(μ₃-PhECH₂EPh₂)(CO)₉ (E = P, As, respectively) and Ru₃(μ-H)₂(μ₃-PPh)(CO)₈(PMePh₂), and Ru₃(μ-H)(μ₃-SBu^t)(CO)₉ gave Ru₃(μ-H)₂(μ₃-S)(CO)₉ by cleavage of PC, AsC, or SC bonds. Both types of reaction occurred with Ru₃(CO)₁₀(dppe) and Ru₃(CO)₁₁]₂(μ-dppe).
