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.

Keywords: 2,4-diaminopteridinium; crystal structure; hydrogen bonding; pteridin-1-ium nitrate; pteridine; ring motifs.
