N,N-Diethyl-2-(4-methyl-benzene-sulfonamido)-benzamide.

ABSTRACT: The asymmetric unit of the title compound, C(18)H(22)N(2)O(3)S, contains two mol-ecules, exhibiting similar conformations [C-S-N-C torsion angles of -82.2?(2) and -70.4?(2)°, and dihedral angles between the mean planes of the aromatic rings of 56.6?(6) and 51.6?(6)° in mol-ecules I and II, respectively]. However, the two independent mol-ecules show distinctly different hydrogen-bonding patterns. In the crystal, molecules I form inversion dimers via pairs of N-H?O hydrogen bonds, whereas for molecules II the N-H?O hydrogen bond is intramolecular. The hydrogen-bonded dimers of I further propagate along the b-axis direction through ?-? inter-actions [the distance between ring centroids is 3.8424?(8)?Å].
