The structures of 7-amino-3-tert-butyl-4-oxo-1,4-dihydropyrazolo[5,1-c][1,2,4]triazine-8-carbonitrile and the corresponding 8-ethyl carboxylate were studied by xray crystal diffraction analysis. Both molecules have a planar conjugated heteronucleus with a marked tendency to form intra- and intermolecular hydrogen bonds. The molecular bond lengths and angles in the single crystals were determined.
