Crystal structure of (4E)-4-(8-methoxy-2H-chromen-2-ylidene)-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one
In the title compound, C20H16N2O3, the phenyl substituent attached to the pyrazole ring makes a dihedral angle of 4.87 (7)° with the rest of the molecule. In the crystal, molecules are connected into inversion dimers of the R22(14) type by pairs of C—H...O interactions. π–π interactions exist betwee...

| Summary: | In the title compound, C20H16N2O3, the phenyl substituent attached to the pyrazole ring makes a dihedral angle of 4.87 (7)° with the rest of the molecule. In the crystal, molecules are connected into inversion dimers of the R22(14) type by pairs of C—H...O interactions. π–π interactions exist between the benzene and pyrazole rings at a distance of 3.701 (1) Å. Similarly, π–π interactions are present at a centroid–centroid distance of 3.601 (1) Å between the oxygen-containing heterocyclic ring and methoxy substituted aromatic ring of a neighbouring molecule. Additional C—H...π and C=O...π interactions are also observed. |
