([mu]2-Chlorido)-([mu]2-pyridine-2-carboxylato-1:2[kappa]N,O:O)-dichlorido(ethanol-[kappa]O)bis[N-hydroxy-1-(pyridin-2-yl)methanimine-[kappa]2N,N']dicobalt(II)

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.
