Hydrogen-bonding synthons of ACZ observed in this study. (a) Molecular diagram showing the hydrogen bonding groups as rigid or flexible (according to Arenas-García et al., 2010BB5, 2012BB6). (b) Synthon 1 between the acetamide and thiadiazole ring of ACZ with carboxylic acid, carboxamide, syn-amide, respectively. (c) Synthon 2 between the sulfonamide group of ACZ and pyridine carboxamides, e.g. NAM, PAM, to give large ring motifs. (d) Synthon 3 connects sulfonamide, thiadiazole N and lactam conformer C. The graph-set notations of ring motifs are given for identification.
