Crystal structure and Hirshfeld surface analysis of 2-Amino-5-{(1E)-1-[(carbamothioylamino)imino]ethyl}-4-methyl-1,3-Thiazol-3-ium chloride monohydrate

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 0.0814Å), 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
