N-{[4-(4-Meth-oxy-benzene-sulfonamido)-phen-yl]sulfon-yl}acetamide.

ABSTRACT: In the title compound, C(15)H(16)N(2)O(6)S(2), the dihedral angle between the benzene rings is 83.2 (3)°. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯O inter-action. In the crystal structure, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds and additional stabilization is provided by weak C-H⋯π inter-actions.

N-[4-(4-Chloro-benzene-sulfonamido)-phenyl-sulfon-yl]acetamide.

Project description:In the title compound, C(14)H(13)ClN(2)O(5)S(2), the dihedral angles between the central benzene ring and the pendant chloro-benzene ring and the N-acetyl group are 82.35?(5) and 79.71?(6)°, respectively, and the overall conformation of the mol-ecule approximates to a U shape. Both the C-S-N-C conformations are gauche, but with opposite senses [torsion angles = -59.29?(15) and 63.68?(16)°]. An intra-molecular C-H?O inter-action generates an S(6) ring. In the crystal, inversion dimers linked by pairs of N-H?O hydrogen bonds generate R(2) (2)(20) loops. A second N-H?O hydrogen bond links the dimers into (101) layers.

The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.

2-Methyl-3-[(4-methyl-phen-yl)sulfon-yl-oxy]-2-{[(4-methyl-phen-yl)sulfon-yloxy]meth-yl}propyl 4-methyl-benzene-sulfonate.

Project description:The title mol-ecule, C(26)H(30)O(9)S(3), adopts an extended conformation whereby two approximately parallel benzene rings [dihedral angle = 8.32?(10)°] are orientated in opposite directions along the pseudo-threefold axis through the central quaternary C atom, while a third ring occupies a position mid-way and face-on to these rings [dihedral angles = 82.28?(10) and 78.81?(7)°]. The crystal packing is dominated by C-H?O contacts and ?-? inter-actions [ring centroid distance = 3.6902?(12)?Å].

A triclinic polymorph of N-[4-(4-methyl-benzene-sulfonamido)-phenyl-sulfon-yl]acetamide.

Project description:In the asymmetric unit of the title compound, C(15)H(16)N(2)O(5)S(2), there are two symmetry-independent mol-ecules which adopt similar conformations, with dihedral angles between the aromatic rings of 59.30 (8) and 61.81 (8)°, and dihedral angles between acetamide group and the benzene ring of 77.08 (10) and 78.40 (10)°. Each type of mol-ecule forms similar one-dimensional polymeric structures extending along the b axis via N-H⋯O hydrogen bonds. These hydrogen bonds generate two types of centrosymmetric motifs, R(2) (2)(8) and R(2) (2)(20). Moreover C-H⋯O inter-actions assemble the mol-ecules into a three-dimensional framework. The crystal structure was determined from a non-merohedral twin [ratio of the twin components = 0.322 (4):0.678 (4)].

N-{4-[(2-Meth-oxy-phen-yl)sulfamo-yl]phen-yl}acetamide.

Project description: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 motif, and these dimers are connected by N-H?O hydrogen bonds, generating a three-dimensional network. Furthermore, a weak C-H?? inter-action helps to reinforce the crystal structure. The O atom in the acetamide group is disordered over two positions with major and minor occupancies of 0.52?(5) and 0.48?(5), respectively.

N-(4-Meth-oxy-benzo-yl)benzene-sulfon-amide.

Project description:In the title compound, C14H13NO4S, the dihedral angle between the aromatic rings is 69.81 (1)°; the dihedral angle between the planes defined by the S-N-C=O segment of the central chain and the sulfonyl benzene ring is 74.91 (1)°. In the crystal, the mol-ecules are linked by weak N-H⋯O hydrogen bonds into C(4) chains running along [100]. The mol-ecules in adjacent chains are linked by weak C-H⋯O inter-actions, generating R 2 (2) (16) dimeric pairs. Weak C-H⋯π inter-actions connect the double chains into (001) sheets.

The dihedral angle between formyl-phenyl and phenyl rings is 47.6?(1)°. The crystal packing features C-H?O hydrogen-bond inter-actions.
