6-Chloro-4-(4-methylphenoxymethyl)-2H-chromen-2-one
In the title compound, C(17)H(13)ClO(3), the coumarin and phen-oxy moieties are essentially co-planar, making a dihedral angle of 1.99 (7)°. The phen-oxy moiety is oriented anti-periplanar with respect to the coumarin ring as indicated by the C-C-O-C angle of -179.97 (16)°. In the crystal, the sheet-like packing is stabilized by inter-molecular C-H⋯O and C-H⋯Cl hydrogen bonds.

The title compound, C(12)H(7)ClN(2)O(2)S, crystallizes with two mol-ecules in the asymmetric unit. The mol-ecular conformation is roughly planar for both these mol-ecules with maximum deviations of 0.177 (3) and 0.076 (4) Å from their respective mean planes. In the crystal, strong N-H⋯N and weak but highly directional C-H⋯O hydrogen bonds provide the links between the mol-ecules. The structure ...

The non-H atoms of the title compound, C(11)H(6)BrFO(3), are essentially coplanar (r.m.s. deviation for all non-H atoms = 0.074 Å). In the crystal, the molecules are linked by C-H⋯O and C-H⋯Br inter-actions.
متن کامل3-Benzyl-2H-chromen-2-one
The title compound, C(16)H(12)O(2), is a coumarin which was isolated from stones of the Chinese traditional medicine Clausena lansium. The pyrone ring is almost planar, with a mean deviation of 0.0135 (4) Å. The benzene ring (A) of the benzopyrone unit forms dihedral angles of 1.82 (5) and 72.86 (2)° with the pyrone ring and the substituent benzene ring, respectively. The crystal structure is s...
متن کامل2-Chloro-3-[(2-oxo-2H-chromen-6-yl)amino]naphthalene-1,4-dione
In the title compound, C19H10ClNO4, the dihedral angle between the naphtho-quinone and coumarin rings is 48.99 (6)°. In the crystal, mol-ecules are linked by strong N-H⋯O hydrogen bonds into chains with graph-set motif C(6) along [101]. The packing also features π-π stacking inter-actions between naphtho-quinone and coumarin rings [centroid-to-centroid distances = 3.7679 (12) and 3.6180 (13) Å].
