N-(2-Formyl-phen-yl)-4-meth-oxy-N-(4-meth-oxy-phenyl-sulfon-yl)benzene-sulfonamide.

ABSTRACT: In the title compound, C(21)H(19)NO(7)S(2), the dihedral angles between the formyl-phenyl ring and the two meth-oxy-phenyl rings are 33.87 (9) and 41.00 (10)°. The S atoms have a distorted tetra-hedral geometry and the N atom shows a trigonally planar [r.m.s. deviation = 0.0437 (13) Å] coordination. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.

N-(4-Meth-oxy-phen-yl)benzene-sulfonamide.

Project description:In the title compound, C(13)H(13)NO(3)S, the benzene ring of the benzene-sulfonamide moiety is disordered with an occupancy ratio of 0.56?(3):0.44?(3), the disorder components being twisted at and angle of 21?(1)° to each other. The meth-oxy-benzene group is roughly planar (r.m.s. deviation = 0.0144?Å) and the amide N atom is displaced from this plane by 0.090?(6)?Å. The dihedral angles between the meth-oxy-benzene group and the major and minor occupancy components of the disordered benzene ring are 54.6?(4) and 62.9?(5)°, respectively. In the crystal, infinite polymeric chains are formed along [100] due to inter-molecular N-H?O hydrogen bonding. Weak C-H?? inter-actions are also present in the crystal.

Project description:In the title compound, C(13)H(12)ClNO(3)S, the dihedral angle between the two aromatic rings is 73.94?(9)°. An intra-molecular C-H?O hydrogen bond occurs. In the crystal, inter-molecular N-H?O hydrogen bonds connect the mol-ecules to centrosymmetric dimers, forming an R(2) (2)(8) ring motif. The packing is consolidated by C-H?O hydrogen bonds and weak ?-? inter-actions [centroid-centroid distances = 3.81?(3) and 3.81?(3)?Å].

Project description:In the title compound, C(14)H(15)NO(3)S, the geometry around the S atom of the SO(2) group is distorted tetra-hedral. The meth-oxy- and methyl-substituted aromatic rings are oriented at a dihedral angle of 71.39?(9)°. Inter-molecular N-H?O hydrogen bonds form inversion dimers, which stabilize the crystal structure.

N-(4-Acetyl-phen-yl)-4-meth-oxy-benzene-sulfonamide.

Project description:The title compound, C15H15NO4S, was obtained by the condensation of 4-amino-aceto-phenone and 4-meth-oxy-benzene-sulfonyl chloride. The dihedral angle between the benzene rings is 86.56?(9)° and the mol-ecule has an approximate V-shaped conformation. The C atom of the meth-oxy group is roughly coplanar with its attached ring [deviation = 0.177?(3)?Å], as is the methyl C atom of the acetyl group with its ring [deviation = 0.065?(2)?Å]. An intra-molecular C-H?O inter-action generates an S(6) ring. In the crystal, N-H?O and C-H?O hydrogen bonds link the mol-ecules into [010] chains. Weak C-H?? inter-actions are also observed.

Project description:In the title mol-ecule, C(20)H(19)NO(3)S, the dihedral angle between the phenyl rings is 48.93?(18)°, and they make dihedral angles of 38.37?(17) and 86.50?(19)° with the benzene ring.
