Chemical compound

Molybdocene dihydride is the organomolybdenum compound with the formula (η5-C5H5)2MoH2. Commonly abbreviated as Cp2MoH2, it is a yellow air-sensitive solid that dissolves in some organic solvents.

The compound is prepared by combining molybdenum pentachloride, sodium cyclopentadienide, and sodium borohydride.[1][2] The dihydride converts to molybdocene dichloride upon treatment with chloroform.

The compound adopts a "clamshell" structure where the Cp rings are not parallel.[3]
