Abstract

The title compound [systematic name: 6-amino-5-formyl-1,3-dimethylpyrimidine-2,4(1H,3H)-dione monohydrate], C7H9N3O3 center dot H2O, has been reexamined at 120 K. The improved precision of the intramolecular dimensions provides evidence for a polarized molecular-electronic structure, and the molecular components are linked by one N - H center dot center dot center dot O and two O - H center dot center dot center dot O hydrogen bonds into two interwoven three-dimensional frameworks, which are weakly linked by the longer component of a three-centre N - H center dot center dot center dot(O)(2) hydrogen bond.
