Abstract: The asymmetric unit of the title compound, [Co(C₃₆H₄₄N₄)]·2C₇H₅NO₃, is composed of one half of the complex, arranged about an inversion center, and a complete 2-nitrobenzaldehyde (NBA) molecule. The structure consists of columns that contain interleaved molecules of NBA and [Co^II(OEP)] (OEP is 2,3,7,8,12,13,17,18-octaethylporphyrin), which are stacked along the a axis. The Co^II atom is involved in a interaction with the ring of the NBA molecule with a centroid-metal distance of 3.508 (6) Å. There is an intramolecular C-HO hydrogen bond in the NBA molecule.
