7-Diethylamino-2-oxo-2H-chromene-3-carbohydrazide
The asymmetric unit of the title compound, C(14)H(17)N(3)O(3), contains two independent mol-ecules with different conformations of the ethyl groups. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into ribbons extending along the a axis.

In the title compound, C(14)H(15)NO(3), all non-H atoms except for those of the methyl and the disordered ethyl groupare approximately co-planar, the largest deviation from the mean plane being 0.0223 (13) Å at the N atom. In the crystal, the packing of mol-ecules through weak inter-molecular C-H⋯O hydrogen-bonding inter-actions leads to the formation of layers parallel to bc plane. Within thes...
متن کاملCinnamyl 2-oxo-2H-chromene-3-carboxylate
The title compound, C(19)H(14)O(4), was prepared by the reaction of 2-oxo-2H-chromene-3-acyl chloride with cinnamic alcohol. The whole mol-ecule is not planar, the dihedral angle between the planes of coumarin and benzene rings being 13.94 (4)°, but the plane of the coumarin ring and that of the ester group are almost coplanar, making a dihedral angle of 2.9 (1)°. In the crystal structure, weak...
متن کاملMenthyl 2-oxo-2H-chromene-3-carboxylate
The title compound, C(20)H(24)O(4), was synthesized from the reaction of 2-oxo-2H-chromene-3-acyl chloride and menthol. The mean plane of the ester group and that of the four essentially planar (maximum deviation 0.0112 Å) C atoms of the chair-form cyclo-hexyl ring form dihedral angles of 43.8 (3) ° and 81.8 (1)°, respectively, with the mean plane of the coumarin ring system. In the crystal str...
متن کاملMethyl 2-oxo-2H-chromene-3-carboxylate
The title compound, C(11)H(8)O(4), features an almost planar mol-ecule (r.m.s. deviation = 0.033 Å for all non-H atoms). In the crystal, the mol-ecules are linked via C-H⋯O hydrogen bonds, forming two-dimensional networks lying parallel to (1-21).
