Methyl 7-meth-oxy-9-oxo-9H-xanthene-2-carboxyl-ate.

ABSTRACT: The crystal structure of the title compound, C(16)H(12)O(5), is stabilized by C-H?O hydrogen bonds and C=O?? inter-actions; ?-? inter-actions are also present. With respective average deviations from planarity of 0.003?(2) and 0.002?(1)?Å, the xanthone and ester fragments are oriented at an angle of 2.8?(2)° with respect to each other. The mean planes of the xanthone skeleton lie either parallel to each other or are inclined at an angle of 85.5?(2)° in the crystal structure.

The crystal structure of the title compound, C(16)H(12)O(5), is stabilized by C-H⋯O hydrogen bonds and C=O⋯π inter-actions; π-π inter-actions are also present. With respective average deviations from planarity of 0.003 (2) and 0.002 (1) Å, the xanthone and ester fragments are oriented at an angle of 2.8 (2)° with respect to each other. The mean planes of the xanthone skeleton lie either parallel to each other or are inclined at an angle of 85.5 (2)° in the crystal structure. ...[more]

Methyl 9H-xanthene-9-carboxyl-ate.

Project description:The title compound, C(15)H(12)O(3), was obtained unintentionally as the by-product of an attempted recrystallization from methanol of propantheline bromide, an anti-muscarinic drug. The xanthone unit is folded, with a dihedral angle of 24.81 (9)° between the benzene rings. The ester substituent adopts a trans staggered conformation, with a C-C-O-C torsion angle of 178.4 (1)°. The mol-ecules pack in distinct layers, facilitated by C-H⋯π and weak π-π ring inter-actions. A weak C-H⋯O inter-action also occurs; however, no classical hydrogen bonding is observed.

9-Meth-oxy-9-(2-meth-oxy-phen-yl)-9H-xanthene.

Project description:In the title compound, C(21)H(18)O(3), the xanthene system and the meth-oxy-phenyl ring are practically orthogonal with a dihedral angle between their mean planes of 89.27?(3)°. The meth-oxy group attached to the phenyl ring makes a C-O-C-C torsion angle of 11.56?(18)°. In the crystal, mol-ecules are linked by C-H?O inter-actions into chains along [010]. Weak C-H?? inter-actions also occur.

(E)-2-Meth-oxy-9-(2-meth-oxy-9H-xanthen-9-yl-idene)-9H-xanthene.

Project description:The title compound, C28H20O4, was synthesized by a bimolecular Zn-HCl reduction in glacial acetic acid using the meth-oxy-substituted xanthone as a starting material. The crystal structure shows that the 2,2'-meth-oxy-bixanthenyl-idene unit is an E-type conformation anti-folded conformer. The mol-ecule lies on an inversion center. The meth-oxy group is almost coplanar with the attached benzene ring, with a C-O-C-C torsion angle of 179.38 (14)°.

Project description:In the title compound, C(19)H(21)NO(4), the dihydro-pyridine ring adopts a distorted screw-boat conformation. The fused cyclo-hexenone ring forms a slightly distorted envelope conformation. The dihedral angle between the mean planes of the benzene and heterocyclic rings is 86.1?(7)°. An intra-molecular C-H?O inter-action occurs. In the crystal, mol-ecules are linked by inter-molecular N-H?O hydrogen bonds, forming an infinite chain along the c axis.

Ethyl 8-meth-oxy-4-oxo-1,4-di-hydro-quinoline-3-carboxyl-ate.

Project description:In the title compound, C13H13NO4, the asymmetric unit contains four independent mol-ecules, each exhibiting an intra-molecular N-H?O hydrogen bond. The ethyl group in one of the four mol-ecules is disordered, with a refined occupancy ratio of 0.295?(16):0.705?(16). A face-to-face stacking inter-action is found between the benzene rings of the quinoline units of two of the mol-ecules [centroid-centroid distance = 3.541?(2)?Å], which are sandwiched by the other two mol-ecules through N-H?O hydrogen bonding. In the crystal, the sandwiched mol-ecules are assembled via stacking inter-actions along the b-axis direction with their translation-symmetry equivalents [centroid-centroid distance = 3.529?(2)?Å], and are further linked through N-H?O hydrogen bonding. The other two mol-ecules are linked via stacking inter-actions with their inversion-symmetry equivalents [centroid-centroid distances = 3.512?(3) and 3.716?(4)?Å] and via N-H?O hydrogen bonding.

Project description:The title compound, C13H12F3NO3, is almost planar if one excludes the F atoms of the -CF3 group [maximum deviation for the other hetero atoms = 0.069?(1)?Å], and the dihedral angle between the pyrrole and benzene ring of the indole system is 2.54?(8)°.
