5-(4-Fluorophenyl)-2,2,6-trimethyl-4H-1,3-dioxin-4-one
The 1,3-dioxine ring in the title compound, C(13)H(13)FO(3), is in a half-boat conformation with the methyl-bonded C atom 0.612 (2) Å out of the plane defined by the remaining five atoms.

The 1,3-dioxin-4-one ring in the title compound, C(16)H(16)O(3), is in a half-boat conformation with the quaternary O-C(CH(3))(2)-O atom lying 0.546 (1) Å out of the plane defined by the remaining five atoms. The crystal structure is consolidated by C-H⋯O contacts that lead to supra-molecular layers.

The title compound, C(13)H(14)N(2)O(2), an isoxazol-5-one derivative, was synthesized by a one-pot, three-component condensation reaction of methyl acetoacetate, hydroxy-lamine hydro-chloride and 4-(dimethyl-amino)benzaldehyde. All the non-H atoms are co-planar [r.m.s deviation = 0.0039 Å], with a Z configuration about the C=C bond. The dihedral angle between the phenyl ring and the isoxazole r...
متن کامل3-(4-Nitrobenzyl)-4H-chromen-4-one
In the title compound, C16H11NO4, the dihedral angle between the ten-membered chromen-4-one ring system (r.m.s. deviation = 0.0095 Å) and the benzene ring is 86.16 (5)°. In the crystal, mol-ecules are linked into a three-dimensional network by weak C-H⋯O hydrogen bonds. The crystal studied was a non-merohedral twin, with the minor twin component refining to 0.093 (1).
متن کامل5-Hydroxy-7-methoxy-4H-chromen-4-one
The mol-ecular conformation of the title compound, C(10)H(8)O(4), isolated from Laretia acualis, is stabilized by a strong intra-molecular hydrogen bond between the hydroxyl and carbonyl groups. The crystal packing shows π-π stacking inter-actions. The chromene (4H-1-benzopyran-4-one) unit is essentially planar.
