4-Methyl-2-oxo-2H-chromen-7-yl 4-methoxybenzenesulfonate
In the title compound, C(17)H(14)O(6)S, the 2H-chromene ring is essentially planar, with a maximum deviation of 0.016 (1) Å. The dihedral angle between the 2H-chromene and the benzene rings is 54.61 (5)°. The C atom of the meth-oxy group is close to coplanar with its attached ring [deviation = 0.082 (2) Å]. In the crystal, mol-ecules are connected via C-H⋯O hydrogen bonds, forming sheets lying ...

In the asymmetric unit of the title compound, C(16)H(11)FO(5)S, the 2H-chromene ring is essentially planar, with a maximum deviation of 0.040 (2) Å. The dihedral angle between the 2H-chromene ring and the 4-fluoro-phenyl ring is 2.17 (8)°. One of the sulfonamide O atoms is approximately coplanar with the benzene ring [C-C-S-O torsion angle = 166.00 (14)°], whereas the other O atom lies well bel...
متن کامل4-Methyl-2-oxo-2H-chromen-7-yl 4-methylbenzenesulfonate
In the title compound, C(17)H(14)O(5)S, the coumarin ring system is nearly planar, with a maximum deviation of 0.034 (2) Å from the mean plane. The dihedral angle between the benzene ring and the coumarin ring system is 56.11 (6)°. The crystal packing is stabilized by C-H⋯O hydrogen bonding, which forms a three-dimensional framework.
متن کامل2-Oxo-2H-chromen-4-yl propionate
In the title compound, C12H10O4, the atoms of the 2-oxo-2H-chromene ring system and the non-H atoms of the 4-substituent all lie on a crystallographic mirror plane. The mol-ecular structure exhibits an intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, mol-ecules form R 3 (2)(12) trimeric units via C-H⋯O inter-actions which propagate into layers parallel to the a...
متن کامل(7-Chloro-2-oxo-2H-chromen-4-yl)methyl diethylcarbamodithioate
In the title compound, C15H16ClNO2S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.023 (2) Å. In the crystal, C-H⋯O hydrogen bonds give R 2 (1)(7) motifs, which generate [100] chains. C-H⋯π and π-π inter-actions between chromene moieties [shortest ring centroid-centroid distance = 3.6199 (13) Å] consolidate the packing.
