The hydrolysis of (η5-C5Me5)WMe4 leads to the formation of the two compounds (η5-C5Me5)2W2O2(μ-CH2)2 (6) and (η5-C5Me5)2W2O2(μ-CH2)(μ-O) (9), containing both methylidene and oxo moieties in one molecule. Reaction of (η5-C5Me5)MoMe4 with water leads to the trinuclear cluster (η5-C5Me5)3Mo3(μ-O)2(μ-CH2)(μ3-CH) (10) with oxo, methylidene, and methylidyne groups. Compounds 6, 9, and 10 were characterized
