(Z)-1-(4-Methyl-phen-yl)-2-(phenyl-sulfon-yl)ethanone oxime.

Project description:The mol-ecule of the title compound, C(15)H(15)NO(3)S, has a twisted U-shaped conformation: the twist occurs at the central C-S(=O)(2)-C-C-C unit and the benzene ring makes a dihedral angle of 28.74?(7)° with the phenyl ring. The S-C-C=N torsion angle is -88.95?(13)°. In the crystal, inversion dimers linked by pairs of O-H?N hydrogen bonds generate R(2) (2)(6) loops, and C-H?O hydrogen bonds connect the dimers into a three-dimensional network.

1-(4-Fluoro-phen-yl)-2-(phenyl-sulfon-yl)ethanone.

Project description:In the title compound, C(14)H(11)FO(3)S, the unit comprising the ethanone and 4-fluoro-phenyl groups is essentially planar, with an r.m.s. deviation of 0.0084 (2) Å for the ten non-H atoms, and it makes a dihedral angle of 37.31 (10)° with the phenyl ring. In the crystal, mol-ecules are linked by pairs of weak C-H⋯O hydrogen bonds into inversion dimers with R(2) (2)(16) graph-set motifs. The dimers are stacked along the b axis through further C-H⋯O hydrogen bonds.

1-(4-Bromo-phen-yl)-2-(phenyl-sulfon-yl)ethanone.

Project description:The overall conformation of the title mol-ecule, C(14)H(11)BrO(3)S, is L-shaped, as seen in the value of the dihedral angle formed between the terminal benzene rings of 75.44?(13)°. The presence of C-H?O inter-actions leads to the formation of linear supra-molecular chains along the a-axis direction in the crystal structure. These are connected into supra-molecular arrays in the ab plane via C-H?? contacts.

2-(4-Methyl-phen-yl)-1-(phenyl-sulfon-yl)propan-2-ol.

Project description:The title compound, C(16)H(18)O(3)S, features a U-shape mol-ecular structure with a dihedral angle between the terminal benzene rings of 20.8 (1)°. An intra-molecular O-H⋯O hydrogen bond helps to stabilize the mol-ecular structure. Inter-molecular classical O-H⋯O and weak C-H⋯O hydrogen bonding is present in the crystal structure.

1-(1-Benzofuran-2-yl)-2-(phenyl-sulfon-yl)ethanone.

Project description:The overall mol-ecular conformation of the title compound, C(16)H(12)O(4)S, is elongated, the dihedral angle formed between the benzofuran (r.m.s. deviation = 0.018?Å) and benzene rings being 24.81?(6)°. Both sulfonyl O atoms lie to one side of the S-bound benzene ring, and the carbonyl and furan O atoms are syn to each other. Supra-molecular arrays parallel to (101) sustained by C-H?O contacts feature in the crystal packing.

Ethyl 1-(4-methyl-phen-yl)-5-phenyl-4-phenyl-sulfon-yl-1H-pyrazole-3-carboxyl-ate.

Project description:The title compound, C(25)H(22)N(2)O(4)S, features a tetra-substituted pyrazole ring. The dihedral angles formed between the five-membered ring (r.m.s. deviation = 0.007?Å) and the N- and C-bound phenyl rings are 48.10?(7) and 72.01?(7) °, respectively, indicating that the planes through the residues are significantly twisted from the plane through the heterocycle. The ester-CO(2) group is also twisted out of this plane, with an O-C-C-N torsion angle of -29.04?(11)°. The sulfonyl-O atoms lie to one side of the pyrazole plane and the sulfonyl-phenyl ring to the other. The dihedral angle between the two ring planes is 70.63?(7) °. Supra-molecular arrays are formed in the crystal structure sustained by C-H?O and C-H??(pyrazole) inter-actions and methyl-C-H??(N-bound benzene) contacts.

Intra-molecular C-H?O hydrogen bonds are also present.

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].
