In the title complex, [Co(C₁₂H₈N₂)₃](C₂Cl₃O₂)₂, the Co^II ion lies on a twofold rotation axis and is coordinated by six N atoms from three bis-chelating 1,10-phenanthroline ligands in a distorted octahedral environment. The crystal structure is stabilized by weak intermolecular C-HO hydrogen bonds.
