Crystal structure and Hirshfeld surface analysis of (5aS,8aR)-3,5a-dimethyl-8-methylidene-2-oxododecahydrooxireno[2′,3′:6,7]naphtho[1,2-b]furan-6-yl (Z)-2-methylbut-2-enoate extracted from Ferula persica

In the hydrated title salt, C7H12N5S2 +·Cl−·H2O, the asymmetric unit comprises one 2-amino-5-{(1E)-1-[(carbamothioylamino)imino]ethyl}-4-methyl-1,3-thiazol-3-ium cation, one chloride anion and one water molecule of crystallization. The cation is nearly flat (r.m.s. deviation of non-H atoms is 0.0814 Å), with the largest deviation of 0.1484 (14) Å observed for one of the methyl C atoms. In the crystal, the cations are linked by O—H...Cl, N—H...Cl, N—H...O, N—H...S and C—H...S hydrogen bonds, forming a tri-periodic network. The most important contributions to the crystal packing are from H...H (35.4%), S...H/H...S (24.4%), N...H/H...N (8.7%), Cl...H/H...Cl (8.2%) and C...H/H...C (7.7%) interactions.

In the title compound, C6H8N2OS, all atoms except for the methyl H atoms are coplanar, with a maximum deviation of 0.026 (4) Å. In the crystal, pairs of molecules are linked by N—H...N hydrogen bonds, forming R 2 2(8) ring motifs. Dimers are connected by N—H...O hydrogen bonds, forming layers parallel to the (102) plane. Consolidating the molecular packing, these layers are connected by C—H...π interactions between the center of the 1,3-thiazole ring and the H atom of the methyl group attached to it, as well as C=O...π interactions between the center of the 1,3-thiazole ring and the O atom of the carboxyl group. According to a Hirshfeld surface study, H...H (37.6%), O...H/H...O (16.8%), S...H/H...S (15.4%), N...H/H...N (13.0%) and C...H/H...C (7.6%) interactions are the most significant contributors to the crystal packing.
