2-Aminobenzoxazole–oxalic acid (2/1)

Abstract

In the title compound, 2C7H7N2O+·C2O42−, proton transfer from oxalic acid to the N atom of the heterocycle has occurred to form a 2:1 molecular salt. In the extended structure, N—H...O hydrogen bonds link the components into [100] chains, which feature R22(8) and R44(14) loops.
