Crystal Structure of 7-Amino-8-R-3-tert-Butyl-4-Oxo-1,4-Dihyd-ropyrazolo[5,1-c][1,2,4]Triazines
Abstract
The structures of 7-amino-3-tert-butyl-4-oxo-1,4-dihydropyrazolo[5,1-c][1,2,4]triazin-8-carbonitrile and 8-ethyl carboxylate were studied by X-ray crystal diffraction analysis. Both molecules demonstrate planar conjugated heteronucleus with a marked tendency to formation of intra- and intermolecular hydrogen bonds. The molecular bond length and angles in single crystals were investigated.
