In the title compound, [Re2(C10H8N2)(CO)8], both Re atoms have distorted octahedral coordination geometry. The carbonyls of the Re(CO)5 moiety are fully staggered relative to those of the Re(CO)3 unit. We are currently interested in the application of Re‐di­imine complexes as catalysts for the photo‐ and electro‐chemical reduction of CO2. The (2,2′‐bi­pyridine)Re(CO)3. radical, a key intermediate in the [Cl(2,2′‐bi­pyridine)Re(CO)3] catalytic CO2 reduction cycle, is formed by Cl− loss from [Cl(2,2′‐bi­pyridine)Re(CO)3]−.. We synthesized the title compound as a precursor to the (2,2′‐bi­pyridine)Re(CO)3. radical and so that we can ex­amine the structural features of the (2,2′‐bi­pyridine)Re(CO)3 moiety following irradiation of the title compound.
