In the crystal structure of the title salt, C10H16N3O+·C7H5O2, the cations and anions are linked to each other via N—H...O hydrogen bonds, forming infinite chains running along [010]. The crystal structure also features C—H...O and π–π stacking inter­actions, which assemble the chains into supra­molecular layers parallel to (100). The π–π stacking inter­actions are observed between the pyridine rings of inversion-related cations with a centroid–centroid distance of 3.867 (2) Å.

The asymmetric unit of the title compound, C14H22N4O2·0.25C6H14·0.5H2O, contains two independent mol­ecules of 2,4-bis­(pivaloyl­amino)­pyrimidine (M) with similar conformations, one water mol­ecule and one-half n-hexane solvent mol­ecule situated on an inversion center. In one independent M mol­ecule, one of the two tert-butyl groups is rotationally disordered between two orientations in a 3:2 ratio. The n-hexane solvent mol­ecule is disordered between two conformations in the same ratio. The water mol­ecule bridges two independent M mol­ecules via O—H...O, N—H...O and O—H...N hydrogen bonds into a 2M·H2O unit, and these units are further linked by N—H...N hydrogen bonds into chains running in the [010] direction. Weak C—H...O inter­actions are observed between the adjacent chains.
