Abstract: The title complexes, [M(C₅O₅)(C₁₂H₈N₂)₂], with M = Co^II, Ni^II and Cu^II, all lie across twofold rotation axes, around which two 1,10-phenanthroline ligands are arranged in a chiral propeller manner. The Co^II and Ni^II complexes are isostructural, with octahedral coordination geometry, while the local geometry of the Cu^II complex is severely distorted from octahedral.

Formula: [Co(C₅O₅)(C₁₂H₈N₂)₂], [Ni(C₅O₅)(C₁₂H₈N₂)₂] and [Cu(C₅O₅)(C₁₂H₈N₂)₂]
