5-Methyl­isoxazole-4-carboxylic acid

In the title compound, C(5)H(5)NO(3), the mol­ecule lies on a crystallographic mirror plane with one half-mol­ecule in the asymmetric unit. An intramolecular C—H⋯O inter­action is present. In the crystal, strong inter­molecular O—H⋯N hydrogen bonds result in the formation of a linear chain structure...

description In the title compound, C(5)H(5)NO(3), the mol­ecule lies on a crystallographic mirror plane with one half-mol­ecule in the asymmetric unit. An intramolecular C—H⋯O inter­action is present. In the crystal, strong inter­molecular O—H⋯N hydrogen bonds result in the formation of a linear chain structure along [100], and there are also weak C—H⋯O hydrogen bonds between the chains which help to stabilize the crystal packing.
