Dimanganese decacarbonyl

Dimanganese decacarbonyl, which has the chemical formula Mn₂(CO)₁₀, is a binary bimetallic carbonyl complex centered around the first row transition metal manganese. The first reported synthesis of Mn₂(CO)₁₀ was in 1954 at Linde Air Products Company and was performed by Brimm, Lynch, and Sesny. Their hypothesis about, and synthesis of, dimanganese decacarbonyl was fundamentally guided by the previously known dirhenium decacarbonyl (Re₂(CO)₁₀), the heavy atom analogue of Mn₂(CO)₁₀. Since its first synthesis, Mn₂(CO)₁₀ has been use sparingly as a reagent in the synthesis of other chemical species, but has found the most use as a simple system on which to study fundamental chemical and physical phenomena, most notably, the metal-metal bond. Dimanganese decacarbonyl is also used as a classic example to reinforce fundamental topics in organometallic chemistry like d-electron count, the 18-electron rule, oxidation state, valency, and the isolobal analogy.
