Abstract
Abstract An arylsulfonamide compound, methyl-2-methyl-2-(4-methylphenyl)sulfonamido propanoate, (1), has been synthesised and structurally characterised. Compound (1) has a staggered conformation relative to the S–N bond. The DFT-optimised molecular geometry of (1) agrees closely with that obtained from the crystallographic study. The crystal exhibits cooperation of N–H···O hydrogen bonds with C–H···O and C–H···π(arene) interactions, resulting in a three-dimensional framework featuring R22(8) and R22(10) synthons. The effect of substitution in different arylsulfonamides retrieved from the Cambridge Structural Database (CSD) on the formation of supramolecular synthons has been analysed in terms of graph-set notation. Hydrogen-bond based interactions in (1) have been complemented by molecular electrostatic potential (MEP) surface calculation. Hirshfeld surface analyses of (1) and a few related arylsulfonamides retrieved from the CSD indicate that about 80% of the Hirshfeld surface areas in these compounds are due to H···H and O···H contacts.
