In the title compound, [Mo(C5H4NO2)2O2], the MoVI atom exhibits a distorted octahedral coordination geometry formed by two terminal oxo ligands and two monoanionic O,O-bidentate pyridinone ligands. The two terminal oxo ligands lie in a cis arrangement, the ketonic O atoms of the pyridinone ligands are coordinated trans to the oxo ligands and the deprotonated hydroxyl O atoms are located trans to each other. The crystal structure contains intermolecular N-H...O hydrogen bonds, C-H...O contacts and face-to-face [pi]-[pi] stacking interactions with an interplanar separation of 3.25 (1) Å.
