In the title compound, C(14)H(12)N(2)O(2), the dihedral angle between the phenyl ring and the 3,4-dimethyl-pyrano[2,3-c]pyrazol-6(1H)-one system is 7.28 (6)°. An intra-molecular C-H⋯O inter-action generates an S(6) ring. In the crystal, the mol-ecules are linked by C-H⋯O hydrogen bonds, forming C(8) chains. C-H⋯π and π-π inter-actions [centroid-centroid separation = 3.6374 (12) Å] further consolidate the packing.
在标题化合物C₁₄H₁₂N₂O₂中,苯环与3,4 - 二甲基 - 吡喃并[2,3 - c]吡唑 - 6(1H) - 酮体系之间的二面角为7.28 (6)°。分子内C—H⋯O相互作用形成一个S(6)环。在晶体中,分子通过C—H⋯O氢键相连,形成C(8)链。C—H⋯π和π - π相互作用[质心 - 质心间距 = 3.6374 (12) Å]进一步巩固了堆积。
