<i>N</i>-(4-Nitrophenyl)methanesulfonamide

Abstract

The structure of the title compound (4NPMSA), C7H8N2O4S, closely resembles those of N-phenyl­methane­sulfonamide (PMSA) and N-(3-nitro­phen­yl)methane­sulfonamide (4NPMSA), with slightly different geometric parameters. The substitution of a nitro group at the para position of PMSA does not change the space group, unlike the case of meta substitution (3NPMSA), where it changes from monoclinic P21/c to triclinic P\overline{1} [Gowda, Foro & Fuess (2007c). Acta Cryst. E63, o2337]. The N—H H atom and the methyl­sulfonyl group are trans to one another across the plane of the benzene ring. Thus, the amide H atom is available to a receptor mol­ecule during biological activity. An N—H⋯O hydrogen bond links the mol­ecules into centrosymmetric dimers.
