3,4-Dimethyl-1-phenylpyrano[2,3-c]pyrazol-6(1H)-one
Abstract
In the title compound, C14H12N2O2, the dihedral angle between the phenyl ring and the 3,4-dimethylpyrano[2,3-c]pyrazol-6(1H)-one system is 7.28 (6)°. An intramolecular C—H...O interaction generates an S(6) ring. In the crystal, the molecules are linked by C—H...O hydrogen bonds, forming C(8) chains. C–H...π and π–π interactions [centroid–centroid separation = 3.6374 (12) Å] further consolidate the packing.
