N-[4-(p-Toluenesulfonamido)phen-ylsulfon-yl]acetamide.

ABSTRACT: In the title compound, C(15)H(16)N(2)O(5)S(2), the dihedral between the two aromatic rings is 81.33 (6)°. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further connected via N-H⋯O hydrogen bonds into a chain running along [01].

N-[4-(Azetidin-1-ylsulfon-yl)phen-yl]-N-(2,4-difluoro-benz-yl)acetamide.

Project description:In the title mol-ecule, C(18)H(18)F(2)N(2)O(3)S, the dihedral angle between the benzene rings is 79.40?(11)°. The 2,4-difluoro-benzyl and azetidine fragments adopt a trans arrangement relative to the central benzene ring. In the crystal, weak C-H?O hydrogen bonds connect mol-ecules into a two-dimensional network parallel to (001).

N-(2-Bromo-phen-yl)-4-methyl-N-(4-methyl-phen-ylsulfon-yl)benzene-sulfonamide.

Project description:In the title compound, C(20)H(18)BrNO(4)S(2), the mean planes formed by the toluene substituents are inclined at a dihedral angle of 45.34?(8)°. The bromo-benzene group is disordered over two positions with an occupancy ratio of 0.74:0.26, resulting in two conformations of the ring; the two rings are oriented at a dihedral angle of 6.6?(6)° with each other. In the crystal structure, weak C-H?O inter-actions connect the mol-ecules in a zigzag manner along the a axis.

N-{4-[(4-Methyl-phen-yl)sulfamo-yl]phen-yl}acetamide.

Project description: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 along the b axis. Intra-molecular C-H?O inter-actions are also observed.

N-{4-[(3,4-Dimethyl-phen-yl)sulfamo-yl]phen-yl}acetamide.

Project description: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.

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-Bromo-phen-yl)-2-(4-chloro-phen-yl)acetamide.

Project description:The title compound, C(14)H(11)BrClNO, consists of chloro-benzene and bromo-benzene units which are linked at either end of the N-methyl-propionamide group. The chloro-benzene unit [maximum deviation = 0.005?(4)?Å] makes a dihedral angle of 68.21?(19)° with the bromo-benzene unit [maximum deviation = 0.012?(3)?Å]. In the crystal, N-H?O hydrogen bonds link the mol-ecules into chains along [010].

Project description:In the title compound, C(16)H(16)BrNO, the dihedral angle between the benzene rings is 69.8?(2)°. In the crystal, N-H?O hydrogen bonds link the mol-ecules into C(4) chains propagating in [100]. Adjacent mol-ecules in the chains are also linked by C-H?O inter-actions which, along with the N-H?O hydrogen bonds, generate R(2) (1)(6) loops.

Project description:In the title compound, C(9)H(11)NO(3)S, the dihedral angle between the benzene ring and the amide group is 76.7?(3)°. In the crystal, mol-ecules are linked by pairs of C-H?O hydrogen bonds into inversion dimers with R(2) (2)(8) ring motifs. The dimers are further connected by N-H?O and C-H?O hydrogen bonds into an infinite tape running parallel to the b-axis direction.

N-[4-(Benzyl-sulfamo-yl)phen-yl]acetamide.

Project description:A folded conformation is found for the title compound, C(15)H(16)N(2)O(3)S, whereby the benzene rings come into close proximity [centroid-centroid distance = 4.0357?(12)?Å and the dihedral angle between them = 24.37?(10)°]. The amide group is coplanar with the benzene ring to which it is bound [C-C-N-C torsion angle = 11.1?(3)°]. In the crystal packing, two-dimensional arrays in the (101) plane are formed via N-H?O hydrogen bonding.

N-[(4-Chloro-phen-yl)sulfon-yl]acetamide.

Project description:The asymmetric unit of the title compound, C(8)H(8)ClNO(3)S, consists of two crystallographically independent mol-ecules (A and B). The dihedral angles between the benzene ring and amide C-C(=O)-NH- plane are 87.6?(3) (mol-ecule A) and 86.0?(3)° (mol-ecule B). In the crystal, the independent mol-ecules are alternately linked by N-H?O hydrogen bonds into an infinite chain along the b axis. Short inter-molecular Cl?Cl contacts [3.2882?(5) and 3.2812?(5)?Å] are also observed.
