ABSTRACT: In the title compound, C(8)H(7)ClO(2), the hydroxyl and aldehyde groups are co-planar with the benzene ring [maximum deviation 0.018?(3)?Å], and the Cl-C-C plane is almost perpendicular to the benzene ring [dihedral angle 83.7?(2)°]. An intra-molecular O-H?O hydrogen bond occurs between the hydroxyl and aldehyde groups.

2-[(2-Chloro-phen-yl)(hy-droxy)meth-yl]phenol.

Project description:In the title compound, C13H11ClO2, the dihedral angle between the mean planes of the 2-chloro-phenyl and phenol rings is 87.4?(9)°. The methyl hy-droxy group lies nearly perpendicular to the plane of its attached benzene ring [O-C-C-C torsion angle = 84.3?(3)°]. The two hy-droxy groups lie on the same side of the mol-ecule and are in a slightly twisted gauche conformation [O-C-C-O torsion angle = 77.1?(8)°] to each other. In the crystal, O-H?O hydrogen bonds between nearby methyl-hydroxy groups form dimers in alternating pairs aligned diagonally along the b axis. A view along the c axis reveals a hexa-meric aggregate mediated by a ring of six O-H?O hydrogen bonds generating an R 6 (6)(12) motif loop.

Project description:In the title compound, C13H9ClN2O, the dihedral angle between the acrylo-nitrile C=C-CN plane and the quilonine ring system is 71.3?(2)°. In the crystal, mol-ecules are linked by O-H?N hydrogen bonds, forming chains along [01-1]. The chains are linked into a three-dimensional network through C-H?N inter-actions.

Methyl 2-[(2-chloro-quinolin-3-yl)(hy-droxy)meth-yl]acrylate.

Project description:There are two independent mol-ecules (A and B) in the asymmetric unit of the title compound, C14H12ClNO3. The mean planes of the methyl ester unit (Cmeth-yl-O-C=O; r.m.s. deviation = 0.051 Å for mol-ecule A and 0.016 Å for mol-ecule B) and the chloro-quilonine ring system (r.m.s. deviation = 0.023 Å for mol-ecule A and 0.014 Å for mol-ecule B) form dihedral angles of 63.5 (1)° in mol-ecule A and 78.1 (1)° in mol-ecule B. The main difference between the two independent mol-ecules is reflected in the (H)O-C-C=C(H2) torsion angle which is -109.7 (2)° in mol-ecule A and 10.6 (2)° in mol-ecule B. An intra-molecular O-H⋯O hydrogen bond is observed in mol-ecule A. In the crystal, mol-ecules A and B are linked into pairs via bifurcated O-H⋯(N,Cl) hydrogen bonds and a weak C-H⋯O hydrogen bond links pairs of mol-ecules into chains along [100].

4-Hy-droxy-3-meth-oxy-benzaldehyde thio-semicarbazone.

Project description:In the title compound, C9H11N3S, there is an intra-molecular O-H⋯O hydrogen bond involving the OH group and the adjacent methoxy O atom. The mol-ecule is essentially planar, with the maximum deviation from the mean plane of the non-H atoms being 0.1127 (14) Å for the methyl C atom. In the crystal, mol-ecules are connected via centrosymmetric pairs of N-H⋯S and O-H⋯O hydrogen bonds into a two-dimensional network parallel to (10-3).

2-Hy-droxy-4-meth-oxy-benzaldehyde thio-semicarbazone.

Project description:The title Schiff base compound, C(9)H(11)N(3)O(2)S, was prepared by the reaction of equimolar quanti-ties of 2-hy-droxy-4-meth-oxy-benzaldehyde with thio-semicarbazide in methanol. The mol-ecule adopts a trans configuration with respect to the azo-methine group and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O and N-H⋯S hydrogen bonds, forming a three-dimensional network.

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.

rac-4-Chloro-2-[({2-[(3-chloro-6-hy-droxy-2,4-dimethyl-benz-yl)(meth-yl)amino]-prop-yl}(meth-yl)amino)-meth-yl]-3,5-dimethyl-phenol.

Project description:The title compound, C(23)H(32)Cl(2)N(2)O(2), a potential chiral ligand for coordination chemistry, was prepared by a two-step reaction. The mol-ecule is located on a crystallographic centre of inversion. As a result, the methyl group bonded to the methyl-ene group is disordered over two equally occupied positions, sharing the same site as the H atom of the chiral C atom. As a further consequence of the crystallographic centrosymmetry, the 1,2-diamino-propane unit adopts an anti-periplanar conformation and the two benzene rings are coplanar. The central chain is in an all-trans arrangement. An intra-molecular O-H?N hydrogen bond makes an S(6) ring motif. A C-H?? inter-action links the mol-ecules into one-dimensional chains along the [001] direction.

5-Chloro-2-hy-droxy-benzaldehyde 4-ethyl-thio-semicarbazone.

Project description:In the title compound, C(10)H(12)ClN(3)OS, the -C=N-N-C- chain bridging the ethyl-imino group and the benzene ring adopts an extended conformation with a C-N-N-C torsion angle of -171.98?(11)°. The imino H atom of the chain is a hydrogen-bond donor to the S atom of an inversion-related mol-ecule, forming a supra-molecular dimer. The hy-droxy H atom is intra-molecularly hydrogen bonded to the azomethine N atom.

2-Hy-droxy-3-meth-oxy-benzaldehyde (o-vanillin) revisited.

Project description:The structure of ortho-vanillin, C(8)H(8)O(3), has been revisited with modern methods and at low temperature (100?K). The previous structure [Iwasaki et al. (1976 ?). Acta Cryst. B32, 1264-1266] is confirmed, but geometric precision is improved by an order of magnitude. The C atom of the meth-oxy group lies close to the benzene ring plane, which is the most common geometry for -OMe groups lying ortho to -OH groups on an aromatic ring. The crystal structure displays one intra-molecular O-H?O and three weak inter-molecular C-H?O hydrogen bonds.

2-Hy-droxy-3-meth-oxy-methyl-5-methyl-benzaldehyde.

Project description:In the title mol-ecule, C(10)H(12)O(3), all non-H atoms lie in a common plane (r.m.s deviation = 0.010 Å). The mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond.
