In the title mol-ecule, C(22)H(16)N(2), the pyrazine ring deviates very slightly from planarity [maximum deviation 0.044 (3) Å], tending towards a twist-boat conformation. The phenyl ring at position 3 makes dihedral angles of 64.0 (2) and 45.8 (2)°, respectively, with the phenyl rings at positions 2 and 5. The dihedral angle between the phenyl rings at positions 2 and 5 is 49.7 (2)°. A C-H⋯π inter-action is found in the crystal structure, but no classical hydrogen bonds form.
在标题分子C₂₂H₁₆N₂中，吡嗪环与平面的偏差非常小[最大偏差为0.044(3)Å]，趋于扭船构象。3位的苯环与2位和5位的苯环分别形成64.0(2)°和45.8(2)°的二面角。2位和5位苯环之间的二面角为49.7(2)°。在晶体结构中发现了C—H⋯π相互作用，但未形成经典氢键。
