Supramolecular synthons and molecular packing in ACZ binary systems. (a), (b) ACZ–NAM (1:1) displays ACZ sulfonamide N—H⋯O and N—H⋯N hydrogen bonds with NAM amide dimers and pyridine N motifs. (c), (d) ACZ–VLM (1:2) where one VLM forms a hydrogen bond with the amidediazole–amide synthon and the second VLM connects such heterodimer units. (e), (f) CPR homodimers interact with sulfonamide hydrate dimer motifs via N—H⋯O and O—H⋯O hydrogen bonds. (g), (h) ACZ–2HP (1:2) shows one equivalent of 2HP to make the heterodimer which is connected by the second 2HP homodimers and sulfonamide N—H⋯O chain. (i), (j) Two-dimensional packing in ACZ–2HP (1:1) makes the binary heterosynthon similar to the previous structure as well as the sulfonamide C(4) catemer. (k), (l) ACZ–MeHP (1:1) is similar to that of ACZ–2HP (1:1). (m), (n) Water molecules are present in the crystal lattice of ACZ–OMeHP hydrate (1:1:1) which connect the binary components of aminodiazole–amide. H atoms are removed in a few diagrams for clarity.
