Abstract
Pyruvic acid oxime (2-hydroxyiminopropanoic acid), C3H5NO3, is a molec ule in which pi resonance between the carboxyl and oxime groups might occur. The pi-electron interaction affects the hydrogen-bond dimension s. Hydrogen-bonded cyclic tetramers of molecules are observed. Only OH ... N and OH ... O hydrogen bonds between the oxime and carboxyl grou ps are observed.
