(Received 9 July 2013; accepted 2 October 2013; online 19 October 2013)

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}, C13H12N2O5, 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.

Comment top

The bond distances and angles were within expected values. The sydnone ring (O1 – C5) and phenyl ring (C31 – C36) of the structure are planar as expected, with all deviations less than 0.1 Å. The angle between the planes of the sydnone (O1 – C5) and phenyl ring (C31 – C36) is 71.94 (8)°. π-atom interactions are seen between the sydnone ring and a symmetry-related O(5) with a distance of 3.2038 (16) Å. Numerous short intra and inter-molecular contacts are noted within the structure. The potential H bonds in the structure are tabulated below.

Experimental top

4-Acetyl-3-(2-ethoxycarbonylphenyl)sydnone was synthesized in 47% yield by heating 3-[2-(ethoxycarbonyl)phenyl]sydnone, acetic anhydride (5 eq), bismuth trifluoromethanesulfonate (25 mole %), and lithium perchlorate (25 mole %) in acetonitrile (2 ml) in a sealed tube at 140°C for 5 h.

Refinement top

The H atoms were all located in a difference map, but those attached to carbon atoms were repositioned geometrically. The H atoms were initially refined with soft restraints on the bond lengths and angles to regularize their geometry (C—H in the range 0.93–0.98, N—H in the range 0.86–0.89 N—H to 0.86 O—H = 0.82 Å) and Uiso(H) (in the range 1.2–1.5 times Ueq of the parent atom), after which the positions were refined with riding constraints.
