Abstract: In the mononuclear title complex, [Co(C₁₂H₁₁N₂O₂)₂(C₂H₆O)₂], the six-coordinate Co^II atom lies on an inversion centre and is coordinated by six O atoms, two from the ethanol molecules and the remaining four from two chelating 4-acetyl-3-methyl-1-phenyl-5-pyrazolonate monovalent anions. O-HN hydrogen bonds involving the ethanol O-H and the pyrazolonate N atoms stabilize the structure.
