摘要：

The fused-ring system is essentially planar. Both N atoms of the five-membered ring are methylated with a delocalized positive charge (resulting in a zwitterionic structure, 1,7,9-trimethyl-2,6-dioxo-1,3-dihydropurin-(7/9)-ium-3-ide). One N atom of the six-membered ring is also methylated and the other has a formal negative charge. The crystal contains three types of hydrogen bonding, O-H...O, O-H...N and C-H...O with O...O 2.918 (3), O...N 2.896(3) and C...O 3.009(3) Angstrom, and H...acceptor 2.05 (4)-2.06(4) Angstrom.
