In the title compound, [Co(C₃H₂O₄)(C₁₄H₁₂N₂)]_n, the Co^II ion is in a distorted octahedral coordination being chelated by a 2,9-dimethyl-1,10-phenanthroline molecule (dmphen) and two carboxylate groups of two malonate ligands The malonate ligand acts in a bridging mode, forming coordination chains along [100]. [pi] - [pi] stacking interactions between dmphen ligands [interplanar distances = 3.414 (4) and 3.447 (4) Å] organize the coordination polymers into supramolecular double chains.
