7-Diethylamino-3-{(E)-4-[(E)-2-(pyridin-4-yl)ethenyl]styryl}-2H-chromen-2-one
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⋯π inter-actions link the mol-ecules into a three-dimen...
متن کامل3-[(E)-3-(2,4-Dichlorophenyl)prop-2-enoyl]-4-hydroxy-2H-chromen-2-one
In the title compound, C(18)H(10)Cl(2)O(4), the chromen-2-one ring system is almost planar [maximum deviation = 0.028 (1) Å] and is inclined at an angle of 16.35 (4)° with respect to the benzene ring. The C=C bond has an E configuration. The mol-ecular conformation is stabilized by an almost symmetric intra-molecular O⋯H⋯O hydrogen bond and a C-H⋯O inter-action, both of which form S(6) ring mot...

In the title mol-ecule, C(18)H(12)O(4), the phenyl ring is twisted by 23.2 (1)° from the mean plane of the chromene system. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into zigzag chains extending in the [010] direction. An intra-molecular O-H⋯O hydrogen bond is also present.

In the title compound, C(19)H(11)N(3)O(2)SClBr, the chromene ring system and the thia-zole ring are each approximately planar, with maximum deviations of 0.033 (3) Å and 0.006 (3) Å, respectively. The mol-ecule adopts an E configuration about the central C=N double bond. The central thia-zole ring makes dihedral angles of 9.06 (14)° and 12.07 (11)° with the chloro-substituted phenyl ring and th...
