Dirhenium decacarbonyl is the inorganic compound with the chemical 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 reductive carbonylation of rhenium.^[2] The compound consists of a pair of square pyramidal Re(CO)₅ units joined via a Re-Re bond, which produces a homoleptic carbonyl complex.^[3]
