3-(4-Biphenyl-1-yl)-3-hydr-oxy-1-phenyl-prop-2-en-1-one.

ABSTRACT: In the title compound, C(21)H(16)O(2), the six crystallographically independent mol-ecules (Z' = 6) all exist in the enolized form. Strong intra-molecular hydrogen bonds are observed: one approximate H-atom-centered O?H?O hydrogen bond, two tautomeric forms O-H?O (three mol-ecules) and O?H-O (two mol-ecules). Only one weak inter-molecular C-H?O hydrogen bond between two neighboring mol-ecules is observed in the crystal structure. In addition, eight very weak non-conventional inter-molecular C-H?? hydrogen-bonding contacts between mol-ecules are observed.

In the title compound, C(21)H(16)O(2), the six crystallographically independent mol-ecules (Z' = 6) all exist in the enolized form. Strong intra-molecular hydrogen bonds are observed: one approximate H-atom-centered O⋯H⋯O hydrogen bond, two tautomeric forms O-H⋯O (three mol-ecules) and O⋯H-O (two mol-ecules). Only one weak inter-molecular C-H⋯O hydrogen bond between two neighboring mol-ecules is observed in the crystal structure.

Project description:Two independent pseudo-enanti-omeric mol-ecules comprise the asymmetric unit in the title compound, C(15)H(14)O(2). While the central O-C-C-C residue approaches planarity [torsion angles = -15.8?(3) (mol-ecule a) and 15.4?(3)° (mol-ecule b)], the benzene rings are approximately orthogonal [the dihedral angles formed between the benzene rings are 62.89?(12) (mol-ecule a) and 80.15?(12)° (mol-ecule b)]. Two-dimensional arrays in the ab plane sustained by O-H?O hydrogen bonding are found in the crystal structure.

Project description:The title compound, C19H20O6, consists of a tetra-substituted benzene ring with one substituent being an ?,?-unsaturated cinnamoyl group, which forms an extended conjugated system in the mol-ecule.

(E)-3-(Biphenyl-4-yl)-1-(3-bromo-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C(21)H(15)BrO, there are two planar rings connected through a conjugated double bond. As it crystallizes in a non-centrosymmetric space group it can be regarded as a good candidate for non-linear optical applications. The mol-ecule adopts an E configuration and the C-C=C-C torsion angle is 177.1?(4)°. The overall conformation of the compound may be described by the values of dihedral angles between the approximately planar parts. The terminal rings are twisted by an angle of 51.52?(9)°, while the biphenyl part is almost planar, the dihedral angle between the planes of the rings being 4.44?(17)°. The unit cell has one long dimension, above 35?Å, characteristic also of a majority of related compounds. The mol-ecules pack head-to-tail along this direction. C-H?? inter-actions are observed in the crystal structure.

(2E)-1-[2-Hydr-oxy-4-(2-methyl-prop-oxy)phen-yl]-3-(4-methyl-phen-yl)prop-2-en-1-one.

Project description:The benzene rings in the title compound, C(20)H(22)O(3), form a dihedral angle of 10.39?(8)°. Overall, the mol-ecule is approximately planar with the exception of one of the terminal methyl groups; excluding this group, the r.m.s. deviation for the remaining 22 non-H atoms is 0.0968?Å. The conformation about the C=C bond is E, and an intra-molecular O-H?O hydrogen bond leads to the formation of an S(6) motif. In the crystal, linear supra-molecular chains are formed along the a axis via C-H?O contacts, and these are connected into double chains via C-H?? inter-actions.
