(E)-Methyl 3-(3,4-dimeth-oxy-phen-yl)-2-[(1,3-dioxoisoindolin-2-yl)meth-yl]acrylate.

ABSTRACT: In the title compound, C(21)H(19)NO(6), the isoindole ring system is essentially planar [maximum deviation = 0.019?(2)?Å for the N atom] and is oriented at a dihedral angle of 51.3?(1)° with respect to the benzene ring. The two meth-oxy groups are almost coplanar with the attached benzene ring [C-O-C-C = 3.7?(4) and 4.3?(4)°]. The mol-ecular conformation is stabilized by an intra-molecular C-H?O hydrogen bond, which generates an S(9) ring motif. In the crystal, mol-ecules are linked through bifurcated C-H?(O,O) hydrogen bonds having R(1) (2)(5) ring motifs, forming chains along the b-axis direction. The crystal packing is further stabilzed by ?-? inter-actions [centriod-centroid distance = 3.463?(1)?Å].

1-[4-(Difluoro-meth-oxy)phen-yl]-N-(3,4-dimeth-oxy-phen-yl)-1H-1,2,4-triazole-3-carboxamide.

Project description:Two crystallographically independent mol-ecules, A and B, with similar conformations are present in the asymmetric unit of the title compound, C(18)H(16)F(2)N(4)O(4). In mol-ecule A, the plane of the 1,2,4-triazole ring is tilted relative of the 4-difluoro-meth-oxy-substituted and the 3,4-dimeth-oxy-substituted benzene rings by 6.5 (2) and 16.4 (1)°, respectively. The -CHF(2) group is twisted away from the plane of the benzene ring, with a dihedral angle between the O-C bond of the OCHF(2) group and the plane of the adjacent phenyl ring of 38.6 (3)°. The corresponding parameters for mol-ecule B are 7.7 (1), 9.5 (2) and 25.2 (2)°. In both mol-ecules, the conformations are stabilized by intra-molecular N-H⋯N and C-H⋯O hydrogen bonds. There are also C-H⋯π contacts between the methyl groups and the benzene rings, and π-π stacking inter-actions between the benzene rings of adjacent parallel A mol-ecules [centroid-centroid distance = 3.8942 (17) Å]. π-π inter-actions are also observed between the triazole ring and one of the benzene rings of parallel B mol-ecules [centroid-centroid distance = 3.7055 (16) Å].

(E)-Methyl 2-[(2-formyl-6-meth-oxy-phen-oxy)meth-yl]-3-phenyl-acrylate.

Project description:The title compound, C(19)H(18)O(5), crystallizes with two independent mol-ecules (A and B) in an asymmetric unit in both of which the two aromatic rings are in a bis-ectional orientation as evidenced by the dihedral angle between them [41.7?(1)° in mol-ecule A and 35.6?(1)° in mol-ecule B]. Both mol-ecules adopt an E configuration with respect to the C=C bond. An intra-molecular C-H?O hydrogen-bond occurs in mol-ecule A. The crystal packing features inter-molecular C-H?O inter-actions.
