Abstract: The dinuclear title compound, [Co₂Cl₃(C₆H₄NO₂)(C₆H₆N₂O)₂(C₂H₅OH)], contains two six-coordinate Co^II atoms with different octahedral coordination environments. One Co^II atom is coordinated by two N atoms from one pyridine-2-carbaldehyde oxime ligand, by one terminal and one bridging Cl^- ion, by one O atom from an ethanol molecule, and by one O atom from a bridging pyridine-2-carboxylate (picolinate) anion. The second Co^II atom is coordinated by two N atoms from another pyridine-2-carbaldehyde oxime ligand, one N and one O atom from the bridging picolinate anion, and by one terminal Cl^- and one bridging Cl^- anion. The structure displays intramolecular O-HO and O-HCl hydrogen bonds. Weak C-HCl hydrogen-bonding interactions connect the molecules into a three-dimensional network.
