The asymmetric unit of the title compound, C(22)H(18)N(2)O(2), contains two independent mol-ecules, which differ in the orientations of the benzyl groups with respect to the planar (r.m.s. deviations of 0.031 and 0.020 Å) quinazoline-2,4-dione skeletons [dihedral angles of 73.97 (4) and 70.07 (4)° in the first mol-ecule and 75.63 (4) and 63.52 (3)° in the second]. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯π interactions and aromatic π-π stacking inter-actions [centroid-centroid distance = 3.735 (2) Å].
标题化合物C(22)H(18)N(2)O(2)的不对称单元包含两个独立分子,它们的苄基相对于平面(均方根偏差分别为0.031和0.020 Å)喹唑啉-2,4-二酮骨架的取向不同[第一个分子中的二面角为73.97 (4)和70.07 (4)°,第二个分子中的二面角为75.63 (4)和63.52 (3)°]。晶体结构通过弱分子间C-H⋯O和C-H⋯π相互作用以及芳香π-π堆积相互作用[质心-质心距离 = 3.735 (2) Å]得以稳定。
