By using the combination of density functional theory (DFT) B3LYP/6-311++ G ( d,g ) within polarized continuum (PCM) model, solvent effects on 3-hydroxy-2-quinoxalinecarboxylic acid (3HQC) tautomers were investigated. Geometrical parameters, vibrational frequencies, electronic and energetic ...
The novel ethyl derivative of 3-hydroxy-2-quinoxalinecarboxylic acid has been synthesized for the first time, characterized by FT-IR spectroscopy and single-crystal X-Ray diffraction. The crystal packing is achieved by inter-molecular C–H···N, C–H···O and N–H···O type hydrogen...
