Cycloheptatrienemolybdenum tricarbonyl is the organomolybdenum compound with the formula (C7H8)Mo(CO)3.

It is a red-orange solid that is soluble in nonpolar organic solvents.

The compound is prepared by thermal reaction of the triene with molybdenum hexacarbonyl:[2] The compound is a piano stool complex, consisting of Mo(CO)3 bound to six carbon centers of the triene.

The methylene group projects from the plane of the six coordinated carbon atoms.

[3] The compound reacts with trityl salts to give the cycloheptatrienyl complex:[4]
