چکیده
Two independent mol-ecules comprise the asymmetric unit of the title compound, C(16)H(18)N(2)O(3)S. Small but significant twists about the (S)N-C and S-C bonds differentiate the mol-ecules but the most obvious difference is found in the relative orientation of the meta-methyl groups, which lie on opposite sides of the mol-ecules. Overall, both mol-ecules adopt a U shape but with significant twisting evident, particularly in the second independent mol-ecule [dihedral angles between benzene rings = 63.90 (13) and 35.78 (11)°]. In the crystal, N-H⋯O hydrogen bonds lead to supra-molecular chains with a tubular topology propagating in [100] and C-H⋯O contacts cross-link the chains.

When viewed down the central S⋯N axis of the title compound, C(20)H(26)N(2)O(3)S, it is apparent that the mol-ecule adopts a gauche conformation with all O atoms lying to one side of the central benzene ring; the carbonyl O atom is directed away from the central ring and the N-bound ethyl groups lie to one side of the mol-ecule. Supra-molecular helical chains aligned along the b axis and sustai...

The title mol-ecule, C(15)H(16)N(2)O(3)S, has a twisted U-shaped conformation. The twist occurs in the central C-S(=O)(2)N(H)-C unit with the C-S-N-C torsion angle being -58.38 (14)°. The benzene rings lie to the same side of the mol-ecule and form a dihedral angle of 67.03 (10)°. The crystal packing features N-H⋯O hydrogen bonding, which leads to supra-molecular chains with a tubular topology ...

In the title compound, C(15)H(16)N(2)O(4)S, the S atom has a distorted tetra-hedral geometry [maximum deviation: O-S-O = 118.25 (7)°]. The two aromatic rings make a dihedral angle of 62.67 (10)° with each other. An intra-molecular N-H⋯O hydrogen bond forms an S(6) ring motif. In the crystal, mol-ecules form centrosymmetric dimers via pairwise N-H⋯O inter-actions, forming an R(2) (2)(8) ring mot...
