Abstract

The asymmetric unit of the title compound [systematic name: 4-acetyl-3-(4-meth­oxy­phen­yl)-1,2,3-oxadiazol-3-ium-5-olate], C11H10N2O4, contains four crystallographically independent mol­ecules. The 1,2,3-oxadiazole rings are almost planar [maximum deviations = 0.006 (3), 0.006 (3), 0.002 (3) and 0.009 (3) Å] and form dihedral angles of 55.03 (14), 61.02 (13), 58.36 (14) and 53.79 (15)° with their attached benzene rings. In the crystal, inter­molecular C—H⋯O and C—H⋯N hydrogen bonds link the mol­ecules, forming sheets parallel to (011)
