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.
