Crystal structure of (E)-4-hy-droxy-3-{1-[(4-hy-droxy-phen-yl)imino]-eth-yl}-6-methyl-2H-pyran-2-one.

ABSTRACT: In the title Schiff base, C14H13NO4, which adopts the phenol-imine tautomeric form, the dihedral angle between the planes of the benzene and heterocyclic (r.m.s. deviation = 0.037?Å) rings is 53.31?(11)°. An intra-molecular O-H?N hydrogen bond closes an S(6) ring. In the crystal, mol-ecules are linked by O-H?O hydrogen bonds to generate C(11) chains propagating in the [010] direction. A weak C-H?O link is also observed, leading to the formation of R (5) 5(32) rings extending parallel to the (101) plane.

In the title Schiff base, C14H13NO4, which adopts the phenol-imine tautomeric form, the dihedral angle between the planes of the benzene and heterocyclic (r.m.s. deviation = 0.037 Å) rings is 53.31 (11)°. An intra-molecular O-H⋯N hydrogen bond closes an S(6) ring. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds to generate C(11) chains propagating in the [010] direction. A weak C-H⋯O link is also observed, leading to the formation of R (5) 5(32) rings extending parallel to the (101 ...[more]

4-Hy-droxy-6-methyl-3-[3-(thio-phen-2-yl)acrylo-yl]-2H-pyran-2-one.

Project description:The title compound, C13H10O4S, crystallizes with two mol-ecules in the asymmetric unit in which the rings make dihedral angles of 3.9 (1) and 6.0 (1)°; this planarity is due in part to the presence of an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring in each mol-ecule. Both mol-ecules represent E isomers with respect to the central C=C bond. In the crystal, mol-ecules are linked by C-H⋯O inter-actions into a three-dimensional network.

4-Hy-droxy-3-[(4-hy-droxy-6-methyl-2-oxo-3,6-dihydro-2H-pyran-3-yl)(3-thien-yl)meth-yl]-6-methyl-3,6-dihydro-2H-pyran-2-one.

Project description:The asymmetric unit of the title compound, C(17)H(14)O(6)S, contains four crystallographically independent mol-ecules in which the pyran-one units are essentially planar, with maximum deviations of 0.016 (2), 0.019 (2), 0.025 (2), 0.014 (2), 0.020 (2), 0.010 (2), 0.003 (2) and 0.012 (2) Å. One of the thio-phene rings is disordered over two positions, with an occupancy ratio of 0.739 (4):0.261 (4). The dihedral angles between the two pyran-one rings in the independent mol-ecules are 59.42 (8), 48.67 (8), 60.62 (9) and 51.60 (8)°. In the crystal, mol-ecules are linked through inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.

(E)-Methyl 2-({2-eth-oxy-6-[(E)-(hy-droxy-imino)-meth-yl]phen-oxy}meth-yl)-3-phenyl-acrylate.

Project description:In the title compound, C(20)H(21)NO(5), the dihedral angle between the mean planes through the two rings is 47.1 (8)°. The enoate group assumes an extended conformation. The hy-droxy-ethanimine group is essentially coplanar with the benzene ring, the largest deviation from the mean plane being 0.061 (1) Å for the O atom. In the crystal, mol-ecules are linked into cyclic centrosymmetric dimers with an R(2) (2)(6) motif via pairs of O-H⋯N hydrogen bonds. Inter-molecular C-H⋯O hydrogen bonds form a C(8) chain along the b axis. The crystal packing is further stabilized by C-H⋯π inter-actions.

4-[(E)-({4-[Bis-(2-hy-droxy-eth-yl)amino]-phen-yl}imino)-meth-yl]phenol.

Project description:In the title compound, C(17)H(20)N(2)O(3), the amino N atom is in a planar environment (sum of angles = 360.0°). All hy-droxy H atoms are involved in hydrogen bonding. In the crystal structure, two O-H?O and an O-H?N(imino) hydrogen bond result in the formation of a three-dimensional network. The latter hydrogen bonding causes distortion of the planarity of the 4-HO-C(6)H(4)-CH=N-C(6)H(4)- fragment by rotation around the =N-C(Ph) bond. The crystal studied was a non-merohedral twin [refined BASF parameter for the major component = 0.5293?(7)].

2-{[(4-{[(2-Hy-droxy-phen-yl)(phen-yl)methyl-idene]amino}-phen-yl)imino](phen-yl)meth-yl}phenol.

Project description:The title mol-ecule, C(32)H(24)N(2)O(2), has a crystallographically imposed inversion centre and exists in the crystal as an enol-imine tautomer. The mol-ecular structure is stabilized by two strong intra-molecular O-H⋯N hydrogen bonds. The dihedral angles between the central benzene ring and the mean planes of the phenyl substituents are 59.99 (1) and 62.79 (2)°. In the crystal, the mol-ecules are arranged into (010) layers via C-H⋯π inter-actions.

2-{[(4-{[(2-Hy-droxy-phen-yl)(phen-yl)methyl-idene]amino}-but-yl)imino](phen-yl)meth-yl}phenol.

Project description:The asymmetric unit of the title compound, C(30)H(28)N(2)O(2), comprises half of a potential tetra-dentate Schiff base ligand; an inversion centre is situtated at the center of the butane-diamine spacer. The central methyl-ene segment of the diamine spacer is disordered over two positions with a refined site-occupancy ratio of 0.651 (7):0.349 (7). The phenyl ring and the hy-droxy-substituted benzene ring are almost perpendicular to each other, with a dihedral angle of 87.90 (8) Å. Intra-molecular O-H⋯N hydrogen bonds make S(6) ring motifs.

Crystal structure of (<i>E</i>)-4-hy-droxy-6-methyl-3-{1-[2-(4-nitro-phen-yl)hydrazinyl-idene]eth-yl}-2<i>H</i>-pyran-2-one.

Project description:The title compound, C14H13N3O5 (HMNP), was synthesized by the simple condensation of p-nitro-phenyl-hydrazine with de-hydro-acetic acid (DHA) in a 1:1 molar ratio in ethanol. HMNP has been characterized by using FT-IR, 1H and 13C NMR and UV-Vis spectroscopic and single-crystal X-ray diffraction techniques. The crystal packing reveals strong hydrogen bonds between the NH group and the carbonyl O atom of di-hydro-pyran-one moiety, forming chains along [101]. The thermal stability of the synthesized compound was confirmed by thermogravimetric analysis and it was found to be stable up to 513 K. The UV-Vis spectrum shows the presence of a strong band at λmax 394 nm. 1H NMR and single-crystal X-ray analyses confirmed the presence of the enol form of the ligand and dominance over the keto form. The crystal studied was a non-merohedral twin with the refined ratio of the twin components being 0.3720 (19):0.6280 (19).

Bis{2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine} monohydrate.

Project description:The title compound, 2C(21)H(19)N(3)O(2)·H(2)O, was synthesized by a Schiff base condensation of 2,6-diformyl-pyridine with 2-amino-4-methyl-phenol in ethanol. In the crystal, two mol-ecules of 2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine dimer-ize via hydrogen bonding to a water mol-ecule, which lies on a twofold axis. There are also intra-molecular phenol-imine hydrogen bonds. The dimers are further linked via π-π (phen-yl-pyridine) [centroid-centroid distance = 3.707 (2) Å] and π-π edge-to-edge [3.392 (2) Å] inter-actions. The dihedral angles between the central ring and the two pendant rings are 11.46 (8) and 2.06 (8)° while the pendant rings make a dihedral angle of 10.14 (8)°.

10-(2-Hy-droxy-eth-yl)-9-(2-hy-droxy-phen-yl)-3,3,6,6-tetra-methyl-1,2,3,4,5,6,7,8,9,10-deca-hydro-acridine-1,8-dione.

Project description:The dihydro-pyridine ring in the title compound, C(25)H(31)NO(4), adopts an envelope conformation with the methine C atom representing the flap. The cyclo-hexenone rings also adopt envelope conformations with the C atoms bearing the methyl C atoms representing the flaps. The phenolic hy-droxy group forms an intra-molecular hydrogen bond to one of the two keto O atoms. The hy-droxy group of the N-bonded alkyl chain forms an inter-molecular hydrogen bond to the other keto O atom of an adjacent mol-ecule. The latter hydrogen bond leads to the formation of a helical chain running along the b axis.
