Sažetak
The structures of the three title isomers, namely 4-[(2-methylphenyl)amino]-3- pyridinesulfonamide (I), 4-[(3-methylphenyl)- amino]-3- pyridinesulfonamide (II) and 4-[(4-methylphenyl)amino]-3- pyridinesulfonamide (III), all C12H13N3O2S, differ in their different hydrogen-bonding arrangements. In all three molecules, the conformation of the 4-aminopyridine-3-sulfonamide moiety is conserved by an intramolecular N-H...O hydrogen bond and C-H...O interactions. In the supramolecular structures of all three isomers, similar C(6) chains are formed via intermolecular N-H...N hydrogen bonds. N-H...O hydrogen bonds lead to C(4) chains in (I), and to and R2/2(8) centrosimmetric dimers in (II) and (III). In each isomer, the overall effect of all hydrogen bonds is to form layer structures.
