Homoleptic dinuclear beryllium carbonyl cation complexes have been produced and characterized in the gas phase. Infrared photodissociation spectroscopic and theoretical results confirm that Be 2 (CO) 5 + is a coordination saturated complex that can be assigned to a mixture of two almost isoenergetic structural isomers. Besides a beryllium–beryllium single‐bonded (OC) 2 Be‐Be(CO) 3 + isomer, another structure involving an unusual end‐on and side‐on bridging carbonyl ligand with very low carbonyl stretching frequency is identified.
