Rac-3-(4-Hy-droxy-benz-yl)chroman-4-one.

ABSTRACT: In the racemic title compound, C16H14O3, the ring of the 4-hy-droxy-benzyl substituent group forms a dihedral angle of 80.12?(12)° with the benzene ring of the chromanone system. Two C atoms of the pyran-one ring and the H atoms on the benzyl ?-C atom are disordered over two sites, with site-occupation factors of 0.818?(8) and 0.182?(8). The crystal structure is stabilized by O-H?O hydrogen bonds, which form parallel one-dimensional zigzag chains down the c axis and are inter-connected by both methine C-H?O hydrogen bonds and weak aromatic C-H?? inter-actions, giving a sheet structure lying parallel to [011].

In the racemic title compound, C16H14O3, the ring of the 4-hy-droxy-benzyl substituent group forms a dihedral angle of 80.12 (12)° with the benzene ring of the chromanone system. Two C atoms of the pyran-one ring and the H atoms on the benzyl α-C atom are disordered over two sites, with site-occupation factors of 0.818 (8) and 0.182 (8). The crystal structure is stabilized by O-H⋯O hydrogen bonds, which form parallel one-dimensional zigzag chains down the c axis and are inter-connected by both m ...[more]

6-Hy-droxy-5,7,8-trimethyl-chroman-2-one.

Project description:The title compound, C(12)H(14)O(3), consists of a chromanone unit with an -OH substituent at the 4-position and methyl substituents on the remaining C atoms of the aromatic ring. The fused pyran-one ring adopts a distorted envelope conformation with the methyl-ene group adjacent to the carbonyl carbon as the flap atom. The crystal structure is stabilized by classical O-H?O hydrogen bonds and weak C-H?O and C-H?? inter-actions, generating a three-dimensional network.

3-Hy-droxy-1-(4-meth-oxy-benz-yl)piperidin-2-one.

Project description:The title compound, C13H17NO3, adopts a conformation in which the aromatic ring and the mean plane of the piperidine ring are almost perpendicular to each other [dihedral angle = 79.25?(6)°]. The presence of the carbonyl group alters the conformation of the piperidine ring from a chair to a twisted half-chair conformation. In the crystal, pairs of strong O-H?O hydrogen bonds link the mol-ecules into inversion dimers. Weak C-H?O inter-actions extend the hydrogen-bonding network into three dimensions.

rac-6-Hy-droxy-2,5,7,8-tetra-methyl-chroman-2-carboxamide from synchrotron data.

Project description:The crystal structure of the title water-soluble analogue of vitamin E, trolox amide, C(14)H(19)NO(3), solved and refined against synchrotron diffraction data, contains two mol-ecules in the asymmetric unit. In both molecules, the heterocyclic ring is in a half-chair conformation. The crystal packing features a herring-bone pattern generated by N-H⋯O hydrogen bonds between the hy-droxy and amide groups. O-H⋯O hydrogen bonds also occur.

5-Chloro-6-hy-droxy-7,8-dimethyl-chroman-2-one.

Project description:In the title mol-ecule, C(11)H(11)ClO(3), the fused pyran ring adopts a half-chair conformation. In the crystal, inter-molecular O-H?O hydrogen bonds link mol-ecules into chains along [100]. These chains are inter-connected by weak inter-molecular C-H?O contacts which generate R(2) (2)(8) ring motifs, forming sheets parallel to (001). Tetra-gonal symmetry generates an equivalent motif along b. Furthermore, the sheets are linked along the c axis by offset ?-? stacking inter-actions involving the benzene rings of adjacent mol-ecules [with centroid-centroid distances of 3.839?(2)?Å], together with an additional weak C-H?O hydrogen bond, resulting in an overall three-dimensional network.

Project description:In the title compound, C(18)H(18)O(4), the six-membered chroman-4-one ring adopts an envelope conformation with the C atom bonded to the bridging CH(2) atom as the flap. The dihedral angle between the mean plane of the fused pyranone ring and the dimeth-oxy-substituted benzene ring is 89.72 (2)°. In the crystal, adjacent molecules are linked via C-H⋯π inter-actions.

6-Hy-droxy-7,8-dimethyl-chroman-2-one.

Project description:The title compound, C(11)H(12)O(3), is essentially planar, with an r.m.s. deviation of 0.179?Å from the mean plane through the 14 non-H atoms in the mol-ecule. The benzene ring and the pyranone mean plane are inclined at 13.12?(6)° to one another and the pyran-one ring adopts a flattened chair conformation. In the crystal, O-H?O hydrogen bonds and C-H?O contacts form R(1) (2)(6) rings and link mol-ecules into chains along b. Additional C-H?O contacts generate inversion dimers, with R(2) (2)(8) ring motifs, and form sheets parallel to (-102) which are linked by C-H?? interactions.

4-[(2-Hy-droxy-benz-yl)amino]-pyridinium nitrate.

Project description:The planes of the aromatic rings in the cation of the title salt, C(12)H(13)N(2)O(+)·NO(3) (-), are twisted along the -CH(2)-NH- single bond by 75.3 (1)°. In the crystal, the phenol O, amine N and pyridinium N atoms are hydrogen-bond donors to the O atoms of the nitrate counter-ions. These hydrogen bonds lead to the formation of a layer in the crystal.

Crystal structure of 3-[({2-[bis-(2-hy-droxy-benz-yl)amino]-eth-yl}(2-hy-droxy-benz-yl)amino)-meth-yl]-2-hydroxy-5-methyl-benzaldehyde.

Project description:The non-symmetric title mol-ecule, C32H34N2O5, is based on a tetra-substituted ethyl-enedi-amine backbone. The mol-ecular structure consists of three hy-droxy-benzyl groups and one 2-hy-droxy-5-methyl-benzaldehyde group bonded to the N atoms of the di-amine unit. The ethyl-enedi-amine skeleton shows a regular extended conformation, while the spatial orientation of the phenol arms is governed by hydrogen bonds. In the 2-hy-droxy-5-methyl-benzaldehyde group, an intra-molecular S(6) O-H?O hydrogen bond is observed between the alcohol and aldehyde functions, and the neighbouring phenol arm participates in an intra-molecular S(6) O-H?N hydrogen bond. The third phenol group is involved in a bifurcated intra-molecular hydrogen bond with graph-set notation S(6) for O-H?N and O-H?O intra-molecular hydrogen bonds between neighbouring amine and phenol arms, respectively. Finally, the fourth phenol group acts as an acceptor in a bifurcated intra-molecular hydrogen bond and also acts as donor in an inter-molecular hydrogen bond, which connects inversion-related mol-ecules into dimers with R 4 (4)(8) ring motifs.

(2E)-3-[3-(Benz-yloxy)phen-yl]-1-(2-hy-droxy-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C(22)H(18)O(3), an intra-molecular O-H?O hydrogen bond stabilizes the mol-ecular structure, forming an S(6) ring motif. The central benzene ring forms a dihedral angle of 64.74?(5)° with the phenyl ring and a dihedral angle of 5.58?(5)° with the terminal benzene ring. In the crystal, mol-ecules are linked into columns along the a axis via inter-molecular C-H?O hydrogen bonds. C-H?? inter-actions involving the centroid of the hy-droxy-substituted benzene ring further stabilize the crystal structure.
