N-(2-Hy-droxy-phen-yl)-4-methyl-benzene-sulfonamide.

ABSTRACT: In the title compound, C13H13NO3S, the dihedral angle between the benzene rings is 64.15 (7)° and the C-S-N-C torsion angle is -57.18 (12)°. An intra-molecular N-H⋯O hydrogen bond closes an S(5) ring. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into C(8) chains propagating in [100]. Weak C-H⋯π inter-actions are also observed.

N-(2-Hy-droxy-1,1-dimethyl-eth-yl)-4-methyl-benzene-sulfonamide.

Project description:In the title mol-ecule, C(11)H(17)NO(3)S, the S atom has a distorted tetra-hedral geometry [maximum deviation: O-S-O = 119.08?(9)°]. In the crystal, mol-ecules are connected by inter-molecular N-H?O, O-H?O and C-H?O hydrogen bonds, forming layers of mol-ecules aligned parallel to (110). The 2-methyl-propan-1-ol group of the mol-ecule is disordered over two positions with an 0.592?(4):0.408?(4) occupancy ratio.

N,N-Bis(2-hy-droxy-eth-yl)-4-methyl-benzene-sulfonamide.

Project description:In the title compound C(11)H(17)NO(4)S, an intra-molecular O-H?O hydrogen bond forms an S(8) ring and determines the conformation of the bis-(2-hy-droxy-eth-yl) segment of the mol-ecule, holding the two CH(2)CH(2)OH groups close to coplanar (r.m.s. deviation = 0.185?Å). In the crystal, O-H?O hydrogen bonds link the mol-ecules into zigzag chains along the b axis. Weaker additional C-H?O and C-H?? contacts generate a three dimensional network, with mol-ecules stacked along the b-axis direction.

Project description:In the title mol-ecule, C(10)H(15)NO(3)S, the S atom is bonded in a distorted tetra-hedral geometry. In the crystal structure, inter-molecular N-H?O, O-H?O and weak C-H?O hydrogen bonds connect the mol-ecules to form a two-dimensional network parallel to (100). The 2-methyl-propan-1-ol group is disordered over two orientations with occupancies of 0.570?(3) and 0.430?(3).

The dihedral angle between the benzene rings is 83.9?(1)°. In the crystal, inter-molecular N-H?O hydrogen bonds pack the mol-ecules into a supra-molecular structure.

Project description:The asymmetric unit of the title compound, C(21)H(13)N(3)O(2), contains two independent mol-ecules with a similar structure. In one mol-ecule, the central benzene ring is oriented with respect to the terminal benzene rings at 27.23?(7) and 67.96?(7)°; in the other mol-ecule, the corresponding dihedral angles are 12.42?(7) and 64.55?(7)°. In both molecules, there is a short O-H?N interaction involving the OH group and the adjacent N atom. In the crystal, there are O-H?N hydrogen bonds, and C-H?O and N-H?O interactions linking the molecules to form a three-dimensional network. ?-? stacking between the pyridine and benzene rings and between the benzene rings [centroid-centroid distances = 3.989?(2), 3.705?(2) and 3.607?(2)?Å] may further stabilize the structure. A weak C-H?? inter-action is present in the crystal.
