4-Acetyl-3-[2-(eth­oxy­carbon­yl)phen­yl]sydnone

Sydnones, which contain a mesoionic five-membered heterocyclic ring, are more stable if synthesized with an aromatic substutuent at the N3 position.

Sumario:Sydnones, which contain a mesoionic five-membered heterocyclic ring, are more stable if synthesized with an aromatic substutuent at the N3 position. In the title compound {sys­tematic name: 4-acetyl-3-[2-(eth­oxy­carbon­yl)phen­yl]-1,2,3-oxa­diazol-3-ylium-5-olate}, C(13)H(12)N(2)O(5), the aromatic substitutent is 2-(eth­oxy­carbon­yl)phenyl. Intra- and inter­molecular hydrogen bonds are observed. The inter­planar angle between the sydnone and benzene rings is 71.94 (8)°. π-ring⋯carbon­yl inter­actions of 3.2038 (16) Å arise between the sydnone ring and a symmetry-related C=O group.
