Abstract

The title mol-ecule, C(24)H(18)N(4)O(2), lies on a twofold rotation axis with a dihedral angle of 73.7 (1)° between the mean planes of the symmetry-related pyridine rings. The dihedral angle between unique benzene and pyridine rings is 8.0 (1)°. An intra-molecular O-H⋯N hydrogen bond may influence the mol-ecular conformation. In the crystal structure, there are weak π-π stacking inter-actions with a centroid-centroid distance of 3.7838 (15) Å.

摘要

标题分子C(24)H(18)N(4)O(2)位于一个二重旋转轴上,对称相关吡啶环的平均平面之间的二面角为73.7 (1)°。独特的苯环和吡啶环之间的二面角为8.0 (1)°。分子内的O-H⋯N氢键可能会影响分子构象。在晶体结构中,存在弱的π-π堆积相互作用,质心间距为3.7838 (15) Å。
