Kennedy, A.R. and Khalaf, A.I. and Suckling, C.J. and Waigh, R.D. (2003) Ethyl 5-oxo-2,5-dihydro-4-isoxazolecarboxylate hydroxylamine salt. Acta Crystallographica Section E: Structure Reports, 59 (9). pp. 1410-1412. ISSN 1600-5368 (http://dx.doi.org/10.1107/S1600536803018828)

Abstract

The isoxazole proton is sufficiently acidic to give the title salt, hydroxylammonium 4-(ethyloxycarbonyl)-5-oxo-2,5-dihydroisoxazolide, NH3OH+.C6H6NO4-, in the presence of hydroxylamine. The deprotonation of the heterocyclic ring has a profound effect on its geometry, notably increasing the N-O distance by 0.05 A to 1.433 (2) A.
