• Opis:
  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.;
