5-Methyl-1,2-oxazole-3-carb­oxy­lic acid

In the crystal structure of the title compound, C(5)H(5)NO(3), all the non-H atoms are approximately coplanar: the carb­oxy O atoms deviating by 0.013 (2) and −0.075 (2) Å from the isoxazole ring plane. In the crystal, the molecules form inversion dimers linked by pairs of O—H⋯O hydrogen bonds and t...

description In the crystal structure of the title compound, C(5)H(5)NO(3), all the non-H atoms are approximately coplanar: the carb­oxy O atoms deviating by 0.013 (2) and −0.075 (2) Å from the isoxazole ring plane. In the crystal, the molecules form inversion dimers linked by pairs of O—H⋯O hydrogen bonds and the dimers stack via π–π inter­actions [centroid–centroid distance = 3.234 (2) Å].
