In the title compound, [Re(C 10 H 8 N 2 )(C 6 H 15 O 3 P) 2 (CO) 2 ]PF 6 , the carbonyl ligands are mutually cis and lie trans to the N donors of the 2,2′‐bipyridyl ligand, while the triethoxyphosphine ligands are mutually trans . The Re I centres exhibit approximate octahedral coordination, the major distortions from which arise from the narrow bite angle of the 2,2′‐bipyridyl ligand which is expressed in the N—Re—N angles of 74.0 (3) and 74.3 (3)°. There are two cations and two anions in the asymmetric unit. The title compound is of interest because it has been shown to be a photocatalyst for CO 2 reduction [Ishitani, George, Ibusuki, Johnson, Koike, Nozaki, Pac, Turner & Westwell (1994). Inorg. Chem. 33 , 4712–4717].
