Five plus H 2 gives four : UV irradiation of a bis(amidinate) complex with a [(H)MoMo(H)] core induces reductive elimination of H 2 and formation of a known quintuply bonded MoMo species (see scheme) that reacts back with H 2 to restore [(H)MoMo(H)]. UV irradiation of the bis(hydride) species in benzene and toluene gives arene complexes in which the aromatic hydrocarbon bridges the molybdenum atoms. Dipp=2,6‐diisopropylphenyl.
