RESUMO
The title compound, C13H18N2O2S, adopts a cis conformation between the methyl-benzoyl and thiono groups across their thio-urea C-N bond. However, the methyl-benzoyl group and N2CS thio-urea moiety are twisted by 15.03â (3)°. In the molecule there is an N-Hâ¯O hydrogen bond. In the crystal, mol-ecules are linked by O-Hâ¯O inter-actions, generating chains extending along the c-axis direction.
RESUMO
The title salt, C5H11N2S(+)·C7H4ClO2 (-), comprises a 2-amino-3-ethyl-4,5-di-hydro-1,3-thia-zol-3-ium cation in which the five-membered ring adopts an envelope conformation with the methyl-ene C adjacent to the S atom being the flap, and a planar 3-chloro-benzoate anion (r.m.s. deviation for the 10 non-H atoms = 0.021â Å). The most prominent feature of the crystal packing are N-Hâ¯O hydrogen bonds whereby the two amine H atoms bridge two carboxyl-ate O atoms resulting in the formation of a centrosymmetric 12-membered {â¯HNHâ¯OCO}2 synthon involving two cations and two anions. These aggregates are linked by C-Hâ¯O inter-actions to form a supra-molecular chain along the a-axis direction.
