Mn_{2} (CO)_{10}

is an organometalic compound due to the presence of

(A) $Mn - C$ bond✓ Correct
(B) $Mn - Mn$ bond
(C)Mn - O bond
(D) $C - O$ bond

Answer: (A)

Solution

A compound counts as organometallic when it contains at least one direct metal-carbon bond. In

Mn X_{2} (CO) X_{10}

each manganese is bonded directly to the carbon atoms of its carbonyl ligands, so there are genuine Mn-C bonds, and it is these bonds that make the compound organometallic.
