Abstract

2-Amino-5-nitrothiazole crystallizes from solution in ethanol as a monosolvate, C3H3N3O2S.C2H6O, in which the thiazole component has a strongly polarized molecular-electronic structure. The thiazole molecules are linked into centrosymmetric dimers by paired N-H...N hydrogen bonds [H...N=2.09 Angstrom, N...N=2.960 (6) Angstrom and N-H...N=169degrees], and these dimers are linked by the ethanol molecules, via a two-centred N-H...O hydrogen bond [H...O=1.98 Angstrom, N...O=2.838 (5) Angstrom and N-H...O=164degrees] and a planar asymmetric three-centred O-H...(O)(2) hydrogen bond [H...O=2.07 and 2.53 Angstrom, O...O=2.900 (5) and 3.188 (5) Angstrom, O-H...O=169 and 136degrees, and O...H...O=55degrees], into sheets built from alternating R-2(2)(8) and R-10(10)(38) rings. These sheets are triply interwoven.
