title: N-(4-Methoxy-phen-yl)-tert-butane-sulfinamide.
abstract: In the title compound, C(11)H(17)NO(2)S, the mol-ecules inter-act head-to-tail through N-H⋯OS hydrogen bonds, giving discrete centrosymmetric cyclic dimers. The N-C(ar-yl) bond length [1.4225 (14) Å] is inter-mediate between that in N-phenyl-tert-butane-sulfinamide [1.4083 (12) Å] and the N-C(alk-yl) bond lengths in N-alkyl-alkanesulfinamides (1.470-1.530 Å), suggesting weaker delocalization of electrons over the N atom and the aromatic ring due to the presence of the 4-meth-oxy group.
