Abstract: The dinuclear title compound, [Co2Cl3(C6H4NO2)(C6H6N2O)2(C2H5OH)], contains two six-coordinate CoII atoms with different octahedral coordination environments. One CoII 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 CoII 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-H...O and O-H...Cl hydrogen bonds. Weak C-H...Cl hydrogen-bonding interactions connect the molecules into a three-dimensional network.
