The title complex, [Co 2 (C 2 F 3 O 2 ) 4 (C 5 H 5 N) 4 (H 2 O)], crystallizes as a neutral dinuclear molecule with two crystallographically distinct octahedrally coordinated Co II ions in the asymmetric unit. The metal ions are connected by two μ 2 ‐bridging trifluoroacetate ions and a single μ 2 ‐bridging water molecule. Each cobalt(II) coordination sphere is completed by a further trifluoroacetate ion, which coordinates in a monodentate manner, and also by two pyridine molecules, resulting in local cis ‐CoN 2 O 4 coordination. The water molecule H atoms participate in intramolecular O—H⋯O hydrogen bonds to the pendant O atoms of the monodentate trifluoroacetate ligands.
