The complete molecule of the compound, C6H4N8O3, is generated by a crystallographic twofold rotation axis that runs through the central ring. The flanking ring is twisted by 20.2 (1)° with respect to the central ring. One of the amino H atoms forms an intra­molecular N—H⋯N hydrogen bond; adjacent mol­ecules are linked by N—H⋯N hydrogen bonds forming a chain running along [10-2].

Modification of metal electrode with catalytic nanoparticles is considered as a promising approach to fabricate electrode for efficient oxygen evolution reaction (OER) electrocatalysis. However, the catalytic nanoparticles synthesis and the...
