The sum of bridging carbonyls in W(CO)₆ and Mn₂(CO)₁₀ is

Question

Canvas Classes · Accepted Answer

Strategy:
 Review the established solid-state and gas-phase structures of both given metal carbonyls to count the bridging ligands.

Step 1: Evaluate 
Tungsten hexacarbonyl is a simple mononuclear octahedral complex.
Bridging  requires more than one metal atom.
Bridging carbonyls = 0.

Step 2: Evaluate 
Decacarbonyldimanganese(0) is a dinuclear complex consisting of two  subunits joined solely by a  bond.
Bridging carbonyls = 0.

Step 3: Sum them
Sum = .
