Ethyl (E)-3-(6-methyl-4-oxo-4H-chromen-3-yl)prop-2-enoate.

ABSTRACT: In the title compound, C(15)H(14)O(4), the chromone ring system is close to being planar [maximum deviation = 0.015?(2)?Å]. The double bond of the ethyl prop-2-enoate chain adopts an E conformation and an intra-molecular C-H?O hydrogen bond generates an S6 ring. In the crystal, inversion dimers linked by pairs of C-H?O hydrogen bonds generate R(2) (2)(14) loops. Weak ?-? inter-actions [centroid-centroid distance = 3.8493?(12)?Å] also occur.

In the title compound, C(15)H(14)O(4), the chromone ring system is close to being planar [maximum deviation = 0.015 (2) Å]. The double bond of the ethyl prop-2-enoate chain adopts an E conformation and an intra-molecular C-H⋯O hydrogen bond generates an S6 ring. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R(2) (2)(14) loops. Weak π-π inter-actions [centroid-centroid distance = 3.8493 (12) Å] also occur. ...[more]

Ethyl 2-[2-(4-oxo-4H-chromen-2-yl)phenoxy]acetate.

Project description:In the title flavonoid derivative, C19H16O5, the chromene portion is planar (r.m.s. deviation = 0.022 Å) with the substituents lying closely to the same plane. The dihedral angle between its mean plane and that of the benzene ring is 4.9 (1)°. This planarity is due, in part, to the presence of a strong intramolecular C-H⋯O hydrogen bond and to two weak C-H⋯O contacts. In the crystal, neighboring molecules are linked by a C-H⋯O hydrogen bond and a C-H⋯π interaction, forming chains along the a-axis direction.

Project description:The title co-crystal, 0.95C(20)H(20)O(3)·0.05C(20)H(19)ClO(3), arises as the chloride carried over during the synthesis shares a position with an aromatic H atom; the partial occupancies are 0.947?(2) and 0.053?(2) for H and Cl, respectively. The mol-ecular structure is stabilized by intra-molecular C-H?O contacts, forming pseudo five- and six-membered rings with S(5) and S(6) graph-set motifs, respectively. The crystal structure features ?-? stacking inter-actions between the centroids of the central fused ring systems [centroid-centroid distance = 3.501?(2)?Å].

(E)-4-Methyl-N'-[(4-oxo-4H-chromen-3-yl)methyl-idene]benzohydrazide.

Project description:In the title chromone-tethered benzohydrazide derivative, C18H14N2O3, the 4H-chromen-4-one and the -CH=N-NH-CO- units are each essentially planar, with the largest deviations from thei planes being 0.052?(2) and 0.003?(2)?Å, respectively. The dihedral angles between the 4H-chromen-4-one and the -CH=N-NH-CO- units, the 4H-chromen-4-one unit and the benzene ring of the 4-tolyl group, and the benzene ring of the 4-tolyl group and the -CH=N-NH-CO- unit are 8.09?(7), 9.94?(5) and 17.97?(8)°, respectively. In the crystal, the mol-ecules form two types of centrosymmetric dimers: one by N-H?O hydrogen bonds and the other by ?-? stacking inter-actions between the 4H-chromen-4-one unit and the 4-tolyl group [centroid-centroid distance = 3.641?(5)?Å]. These dimers form one-dimensional assemblies extending along the a-axis direction. Additional ?-? stacking inter-actions between two 4H-chromen-4-one units [centroid-centroid distance = 3.591?(5)?Å] and two 4-tolyl groups [centroid-centroid distance = 3.792?(5)?Å] organize the mol-ecules into a three-dimensional network.

Ethyl (E)-3-(anthracen-9-yl)prop-2-enoate.

Project description:In the asymmetric unit of the title compound, C19H16O2, there are two symmetry-independent mol-ecules (A and B) that differ in the conformation of the ester eth-oxy group. In the crystal, the mol-ecules form inversion dimers via pairs of C-H?O inter-actions. Within the dimers, the anthracenyl units have inter-planar distances of 0.528?(2) and 0.479?(2)?Å for dimers of mol-ecules A and B, respectively. Another short C-H?O contact between symmetry-independent dimers links them into columns parallel to [10-1]. These columns are arranged into (111) layers and there are ?-? stacking inter-actions [centroid-centroid distances = 3.6446?(15) and 3.6531?(15)?Å] between the anthracenyl units from the neighbouring columns. In addition, there are C-H?? inter-actions between the anthracenyl unit of dimers A and dimers B within the same column.
