2-[(2,6-Diisopropyl-phen-yl)imino-meth-yl]-4-iodo-phenol.

ABSTRACT: The asymmetric unit of title compound, C(19)H(22)INO, contains two independent mol-ecules. Classical intra-molecular O-H?N hydrogen bonds stabilize the mol-ecular structures. The crystal structure is stabilized by weak inter-molecular C-H?? and ?-? [centroid-centroid = 3.8622?(18)?Å] inter-actions. In both mol-ecules, the aromatic rings are nearly perpendicular to each other [dihedral angles = 84.26?(17) and 86.69?(15)°].

4-(2-Iodo-benzene-sulfonamido)benzoic acid monohydrate.

Project description:In the mol-ecule of the title compound, C(13)H(10)INO(4)S·H(2)O, the coordination around the S atom is distorted tetra-hedral. The aromatic rings are oriented at a dihedral angle of 74.18?(17)°. Intra-molecular C-H?O hydrogen bonds result in the formation of non-planar five- and six-membered rings, which adopt envelope and twist conformations, respectively. In the crystal structure, inter-molecular N-H?O, O-H?O and C-H?O hydrogen bonds link the mol-ecules. ?-? Contacts between the phenyl rings [centroid-centroid distance = 3.726?(3)?Å] may further stabilize the structure. There is also a C-H?? inter-action.

2-{(E)-[(2Z)-2-(1,2-Di-hydro-phthalazin-1-yl-idene)hydrazinyl-idene]meth-yl}phenol.

Project description:The title compound, C15H12N4O, adopts an E conformation with respect to the azomethine bond and crystallizes in its hydrazinyl-idene tautomeric form. The dihedral angle between the ring systems is 15.98?(7)°. The phenol O-H group forms an intra-molecular O-H?N hydrogen bond. In the crystal, pairs of N-H?N and C-H?O hydrogen bonds link neighbouring mol-ecules into centrosymmetric dimers. These dimers are inter-connected by means of three types of ?-? stacking inter-actions. One, with a centroid-centroid distance of 3.577?(1)?Å [inter-planar separation = 3.4673?(6)?Å], connects adjacent mol-ecules into centrosymmetric dimers. The other two inter-actions, on the outward facing sides of the dimers, are between phenol rings of neighboring mol-ecules [centroid-centroid separation = 3.7907?(13)?Å and inter-planar separation = 3.5071?(8)?Å], and between phthalazin units [centroid-centroid separation = 3.6001?(12)?Å and inter-planar separation = 3.4891?(7)?Å]. In combination, the ?-? inter-actions lead to the formation of infinite layers with mol-ecules stacked along [0-11]. These layers are, in turn, connected with neighbouring layers through the N-H?N and C-H?O hydrogen bonds, yielding a three-dimensional supra-molecular architecture.

Project description:In the title compound, C16H12FIO2S, the dihedral angle between the plane of the benzo-furan ring system (r.m.s. deviation = 0.023?Å) and that of the 2-fluoro-phenyl ring is 39.78?(7)°.

These dimers are further linked by ?-? inter-actions between the furan and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.668?(2)?Å]. The mol-ecules stack along the a-axis direction. In addition, C-H?O hydrogen bonds are observed between inversion-related dimers.
