(2E)-1-(2-Hy-droxy-5-methyl-phen-yl)-3-(4-meth-oxy-phen-yl)prop-2-en-1-one.

ABSTRACT: In the title compound, C(17)H(16)O(3), the dihedral angle between the aromatic rings is 4.59?(7)° and an intra-molecular O-H?O hydrogen bond generates an S(6) ring. In the crystal, adjacent mol-ecules are linked by C-H?O hydrogen bonds, leading to the formation of [001] supra-molecular chains. Weak C-H?? inter-actions consolidate the packing.

In the title compound, C(17)H(16)O(3), the dihedral angle between the aromatic rings is 4.59 (7)° and an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, adjacent mol-ecules are linked by C-H⋯O hydrogen bonds, leading to the formation of [001] supra-molecular chains. Weak C-H⋯π inter-actions consolidate the packing. ...[more]

In the crystal, mol-ecules are linked by O-H?O hydrogen bonds, forming chains along [100]. These chains are further linked by O-H?O hydrogen bonds, forming corrugated sheets lying parallel to (010). There are C-H?? inter-actions present within the sheets.

Crystal structure of (2E)-3-(3-eth-oxy-4-hy-droxy-phen-yl)-1-(4-hy-droxy-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C17H16O4, the dihedral angle between the benzene rings is 21.22?(1)° and the mean plane of the prop-2-en-1-one group makes dihedral angles of 10.60?(1) and 11.28?(1)°, respectively, with those of the hy-droxy-phenyl and eth-oxy-phenyl rings. The eth-oxy substituent forms a dihedral angle of 88.79?(2)° with the the prop-2-en-1-one group, which is found to be slightly twisted. In the crystal, phenolic O-H?O hydrogen bonds to the carbonyl O atom form a two-dimensional supra-molecular network structure lying parallel to (010).

3-Hy-droxy-2-[(2E)-1-(2-hy-droxy-6-oxocyclo-hex-1-en-1-yl)-3-(2-meth-oxy-phen-yl)prop-2-en-1-yl]cyclo-hex-2-en-1-one.

Project description:In the title compound, C(22)H(24)O(5), each of the cyclo-hexenone rings adopts a half-chair conformation. The hy-droxy and carbonyl O atoms face each other and are orientated to allow for the formation of the two intra-molecular O-H?O hydrogen bonds which are typical of xanthene derivatives. In the crystal, weak inter-molecular C-H?O hydrogen bonds link mol-ecules into layers parallel to the ab plane.

Project description:In the title mol-ecule, C19H20O6, the conformation about the C=C bond of the central enone group is E. The dihedral angle formed by the benzene rings is 11.6?(2)°. The hy-droxy group is involved in an intra-molecular O-H?O hydrogen bond. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules into chains along [010].

3-(2-Chloro-3-hy-droxy-4-meth-oxy-phen-yl)-1-(4,5-dimeth-oxy-2-methyl-phen-yl)prop-2-en-1-one.

Project description:The title compound, C(19)H(19)ClO(5), is a chloro derivative of a biologically significant chalcone family. The mean plane of the two substituted benzene rings are twisted by 55.33?(8)° with respect to each other. An intra-molecular C-H?Cl hydrogen bond generates an S(5) graph-set motif. In the crystal, a bifurcated O-H?(O,O) hydrogen bond leads to an R(1) (2)(5) graph-set motif and to the formation of zigzag chains propagating along the c-axis direction. A weak ?-? inter-action involving the methyl-phenyl rings [centroid-centroid distance = 3.8185?(10)?Å] and C-H?? inter-actions also occur.

Crystal structure of (2E)-1-(4-hy-droxy-1-methyl-2-oxo-1,2-di-hydro-quinolin-3-yl)-3-(4-hy-droxy-3-meth-oxy-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C20H17NO5, the dihedral angle between the mean plane of the di-hydro-quinoline ring system (r.m.s. deviation = 0.003 Å) and the benzene ring is 1.83 (11)°. The almost planar conformation is a consequence of an intra-molecular O-H⋯O hydrogen bond and the E configuration about the central C=C bond. In the crystal structure, O-H⋯O hydrogen bonds generate chains of mol-ecules along the [10-1] direction. These chains are linked via π-π inter-actions [inter-centroid distances are in the range 3.6410 (16)-3.8663 (17) Å].

(2E)-3-(3-Bromo-4-meth-oxy-phen-yl)-1-(4-methyl-phen-yl)prop-2-en-1-one.

Project description:The overall shape of the mol-ecule of the title compound, C(17)H(15)BrO(2), can be described by the dihedral angles between three planar fragments: 1-bromo-2-meth-oxy-phenyl ring [maximum deviation = 0.003?(2)?Å], the central prop-2-en-1-one chain [maximum deviation = 0.005?(2)?Å], and the methyl-phenyl ring [maximum deviation = 0.004?(2)?Å]. The terminal planes are twisted by 10.37?(12)°, while the central plane is almost coplanar with the methyl-phenyl ring [3.30?(13)°], but the dihedral angle with the other phenyl ring is significantly larger [8.76?(16)°]. In the crystal, mol-ecules are linked into chains along [001] by three C-H?O hydrogen bonds. These chains inter-act with each other by means of weak ?-? contacts [centroid-centroid distances = 3.73?(1) and 3.44?(1)?Å]. An inter-molecular C-H?Br inter-action also occurs.

(E)-1-[2-Hy-droxy-4,6-bis-(meth-oxy-meth-oxy)phen-yl]-3-phenyl-prop-2-en-1-one.

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. In addition, two meth-oxy-meth-oxy and one hy-droxy group are bonded to the central benzene ring. The dihedral angle between eh rings is 10.22?(10)°. An intra-molecular hydrogen bond is observed between the hy-droxy group and the carbonyl O atom. One of the meth-oxy-meth-oxy substituents is conformationally disordered over two sets of sites with site-occupation factors of 0.831?(3) and 0.169?(3).
