Abstract:
The title compound, C9H9N3O2S, is close to planar with an r.m.s. deviation of 0.032 Å. An intra-molecular N-H⋯N hydrogen bond closes an S(5) ring. In the crystal, mol-ecules are connected into inversion dimers of the R 2 (2)(8) type by pairs of O-H⋯O inter-actions. The dimers are further connected by pairs of N-H⋯S inter-actions, which also complete R 2 (2)(8) ring motifs. The chains of dimers are cross-linked by N-H⋯O bonds and hence R 4 (2)(28) rings are completed. Taken together, these inter-actions lead to infinite sheets propagating in the (122) plane.

Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...

For acyclic saturated monocarboxylic acids, the longest hydrocarbon chain containing the –COOH carbon is identified as the parent chain. Then, the last -e of the parent hydrocarbon name is replaced with a suffix -oic acid.
01:16Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
01:11Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
