2‐Amino‐5‐nitro­thia­zole monoethanol solvate: triply‐interwoven hydrogen‐bonded sheets containing centrosymmetric R(8) and R(38) rings

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 Å, N?N = 2.960 (6) Å and N—H?N = 169°], and these dimers are linked by the ethanol mol­ecules, via a two‐centred N—H?O hydrogen bond H?O = 1.98 Å, N?O = 2.838 (5) Å and N—H?O = 164°] and a planar asymmetric three‐centred O—H?(O)₂ hydrogen bond H?O = 2.07 and 2.53 Å, O?O = 2.900 (5) and 3.188 (5) Å, O—H?O = 169 and 136°, and O?H?O = 55°], into sheets built from alternating (8) and (38) rings. These sheets are triply interwoven.
