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.

In the title coumarin derivative, C(13)H(12)O(4), the 2H-chromene ring system is essentially planar [maximum deviation = 0.047 (1) Å]. An intra-molecular hydrogen bond is observed between the hy-droxy and the ketonic O atoms. In the crystal, pairs of inter-molecular C-H⋯O hydrogen bonds link inversion-related mol-ecules into dimers. Additional inter-molecular C-H⋯O hydrogen bonds further inter-...
متن کامل3-(2-Amino-1,3-thiazol-4-yl)-6-chloro-2H-chromen-2-one
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 ...
متن کامل3-(2-Bromoacetyl)-6-fluoro-2H-chromen-2-one
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-Acetyl-2-fluoro-6H-benzo[c]chromen-6-one
The title compound, C15H9FO3, was obtained in a one-pot synthesis by Suzuki-Miyaura cross-coupling and nucleophilic substitution reaction of 4'-chloro-2',5'-di-fluoro-aceto-phenone with o-(meth-oxy-carbon-yl)phenyl-boronic acid. The asymmetric unit contains two crystallographically independent mol-ecules related by a non-crystallographic inversion centre. There are face-to-face stacking inter-a...
