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.
متن کامل4-(2-Methoxybenzylidene)-2-phenyl-1,3-oxazol-5(4H)-one
The title mol-ecule, C(17)H(13)NO(3), adopts a Z configuration about the central olefinic bond. The 2-phenyl ring is almost coplanar with the plane of the oxazolone ring system, making a dihedral angle of 2.03 (11)°. The crystal structure is stabilized by π-π inter-actions between the oxazolone ring and phenyl ring of a neighbouring mol-ecule [centroid-centroid distance = 3.550 (3)Å], and by tw...

The mol-ecular skeleton of the title mol-ecule, C(11)H(9)NO(3), is approximately planar (r.m.s. deviation = 0.0056 Å); the two rings form a dihedral angle of 6.5 (1)°. In the crystal structure, inter-molecular O-H⋯N hydrogen bonds involving the H atom of the hydr-oxy group and the N atom of the isoxazole ring link mol-ecules into chains running along the c axis.
متن کامل5-Hydroxy-2-methyl-4H-pyran-4-one
The title compound, C(6)H(6)O(3), is a member of the pyrone family. The mol-ecules are planar (r.m.s. deviation of the asymmetric unit is 0.0248 Å, whereas that of the dimer is 0.0360 Å) and they are dimerized due to inter-molecular O-H⋯O hydrogen bonds. The dimers are connected to each other through hydrogen bonds involving the CH(3) group and the hydr-oxy O atom. There are π-π inter-actions b...
