7-Fluoro-6-nitroquinazolin-4(3H)-one
The quinazolinone unit of the title compound, C(8)H(4)FN(3)O(3), is essentially planar, with a maximum deviation of 0.0538 (14) Å for the O atom. The nitro group is twisted by 12.0 (3)° from the mean plane of the quinazolinone ring system. The crystal structure is stabilized by inter-molecular N-H⋯O, C-H⋯N and C-H⋯O hydrogen bonds.
متن کامل6-Chloro-7-fluoro-4-oxo-4H-chromene-3-carbaldehyde
In the title compound, C10H4ClFO3, a chlorinated and fluorinated 3-formyl-chromone derivative, all atoms are essentially coplanar (r.m.s. = 0.0336 Å for the non-H atoms), with the largest deviation from the least-squares plane [0.062 (2) Å] being for a benzene-ring C atom. In the crystal, mol-ecules are linked through stacking inter-actions [centroid-centroid distance between the benzene and py...
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...
متن کامل6-Ethyl-5-fluoro-2-methoxypyrimidin-4(3H)-one
In the title compound, C(7)H(9)FN(2)O(2), the meth-oxy and ethyl groups form dihedral angles of 1.4 (2) and 73.5 (3)°, respectively, with the mean plane of the pyrimidine ring. In the crystal structure, two mol-ecules are linked by a pair of N-H⋯O hydrogen bonds, forming a centrosymmetric dimer.
