Abstract: In the title compound, [Re(C₁₀H₈N₂)(C₆H₁₅O₃P)₂(CO)₂]PF₆, 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 CO₂ reduction [Ishitani, George, Ibusuki, Johnson, Koike, Nozaki, Pac, Turner & Westwell (1994). Inorg. Chem. 33, 4712-4717].
