Dirhenium decacarbonyl is an inorganic compound with the formula Re₂(CO)₁₀. Commercially available, it is used as a starting point for the synthesis of many rhenium carbonyl complexes. It was first reported in 1941 by Walter Hieber who prepared it by carbonylation of Re₂O₇. The compound consists of a pair of square pyramidal Re(CO)₅ units joined via a Re-Re bond. Mn₂(CO)₁₀ and Tc₂(CO)₁₀ adopt the same structure.

Reaction with various halogens cleave the Re-Re bond:

Re₂(CO)₁₀ + X₂ → 2 Re(CO)₅X (X = Cl, Br, I)

When bromine is used, bromopentacarbonylrhenium(I) is formed; it is itself an intermediate for many more rhenium complexes.
