title: Crystal structure of 2,4-di-amino-7-(hydroxy-meth-yl)pteridin-1-ium nitrate.
abstract: In the crystal of the title mol-ecular salt, C7H9N6O(+)·NO3 (-), the cations and anions are linked via N-H⋯O and O-H⋯O hydrogen bonds, forming sheets parallel to (100). Within the sheets there are numerous hydrogen-bonding ring motifs.
