Abstract: In the title complex, [Co(C₄O₄)(C₁₂H₈N₂)(H₂O)₂]_n, the Co^II atom exhibits a slightly distorted octahedral coordination geometry involving two N atoms from 1,10-phenanthroline, two O atoms from two acetylenedicarboxylate (ace^2-) dianions and two water O atoms. The ace^2- ligand acts in a bis-monodentate mode to connect two adjacent Co^II atoms, forming chains along the b axis. A three-dimensional supramolecular architecture is constructed via O-HO hydrogen bonds and - interactions.
