7-Di-ethyl-amino-3-{(E)-4-[(E)-2-(pyridin-4-yl)ethen-yl]styr-yl}-2H-chromen-2-one.

ABSTRACT: In the title coumarin derivative, C28H26N2O2, the coumarin unit is approximately planar, with a maximum deviation of 0.048?(3)?Å. The central benzene ring is oriented at dihedral angles of 30.15?(14) and 10.51?(11)°, respectively, to the pyridine ring and coumarin ring system. In the crystal, weak C-H?O and C-H?N hydrogen bonds and weak C-H?? inter-actions link the mol-ecules into a three-dimensional supra-molecular architecture.

3-{2-[2-(Diphenyl-methyl-ene)hydrazin-yl]thia-zol-4-yl}-2H-chromen-2-one.

Project description:In the title compound, C(25)H(17)N(3)O(2)S, the coumarin ring system is essentially planar with a maximum deviation of 0.019?(2)?Å. A weak intra-molecular C-H?O hydrogen bond stabilizes the mol-ecular structure, so that the coumarin plane is approximately coplanar with the thia-zole ring, making a dihedral angle of 2.5?(10)°. The two phenyl rings are nearly perpendicular to each other, with a dihedral angle of 81.44?(12)°. In the crystal structure, the mol-ecules are linked into an infinite chain along the b axis by inter-molecular C-H?O hydrogen bonds. Weak C-H?? inter-actions are observed between the chains.

Project description:In the title compound, C17H18ClNO5, which was synthesized by reacting 4-chloro-3-formyl-coumarin, acetic acid and tert-butyl isocyanide, the acetamido side chain is convoluted with ring-to-side chain C-C-C-C, C-C-C-N and C-C-N-C torsion angles of -123.30?(14), -135.73?(12) and 176.10?(12)°, respectively.

Crystal structure of 3-[2-(4-methyl-phen-yl)ethyn-yl]-2H-chromen-2-one.

Project description:The coumarin ring system in the title asymmetric alkyne, C18H12O2, is approximately planar (r.m.s. deviation of the 11 non-H atoms = 0.048?Å), and is inclined with respect to the methyl-benzene ring, forming a dihedral angle of 33.68?(4)°. In the crystal, supra-molecular zigzag chains along the c-axis direction are formed via weak C-H?O hydrogen bonds, and these are connected into double layers via weak C-H?? inter-actions; these stack along the a axis.

N-(2-Oxo-2H-chromen-3-yl)cyclo-hexane-carboxamide.

Project description:In the title compound, C16H17NO3, the coumarin moiety is essentially planar [maximum deviation from the mean plane formed by the C and O atoms of the coumarin = 0.0183?(12)?Å] and that the cyclo-hexane ring adopts the usual chair conformation. The dihedral angle between the mean plane of the coumarin residue and the plane of the amide residue (defined as the N, C and O atoms) is 18.9?(2)°. There are two intra-molecular hydrogen bonds involving the amide group. In one, the N atom acts as donor to the ketonic O atom and in the other, the amide O atom acts as acceptor of a C-H group of the coumarin. In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H?O contacts and these dimers are linked into pairs by weak C-H?O hydrogen bonds. The combination of these inter-actions creates a chain of rings which runs parallel to [2-10]. C-H?? and ?-? [centroid-centroid distance = 3.8654?(10)?Å] inter-actions are also observed.
