4-Acetyl-3-(p-anis-yl)sydnone.

ABSTRACT: THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: 4-acetyl-3-(4-meth-oxy-phen-yl)-1,2,3-oxadiazol-3-ium-5-olate], C(11)H(10)N(2)O(4), contains four crystallographically independent mol-ecules. 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, inter-molecular C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules, forming sheets parallel to (011).
