Structural study and Hirshfeld surface analysis of ()-4-(2-meth-oxy-benzyl-idene)-3-phenyl-isoxazol-5(4)-one.

The title compound, CHNO, adopts a configuration about the C=C bond. The isoxazole and meth-oxy-benzyl-idene rings are almost coplanar with a dihedral angle of 9.63 (7)° between them. In contrast, the phenyl substituent is twisted significantly out of the plane of the oxazole ring, with the two rings inclined to each other by 46.22 (4)°. The crystal structure features C-H⋯O, C-H⋯N and C-H⋯π hydrogen bonds and π-π contacts. An analysis of the Hirshfeld surfaces points to the importance of H⋯H, H⋯C/C⋯H and H⋯O/O⋯H contacts. The included surface areas of the title compound were compared to those of the isomeric structure ()-4-(4-meth-oxy-benzyl-idene)-3-phenyl-isoxazol-5(4)-one [Zhang (2015 ▸). , , 7316-7322].
