The asymmetric unit of the potential mono-Schiff base ligand title compound, C(13)H(10)N(4), contains two crystallographically independent mol-ecules, A and B. In mol-ecule A, the two rings are twisted from each other by 13.90 (18)°. By contrast, the dihedral angle between the two rings in mol-ecule B is 0.67 (19)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯N inter-actions via R(4) (4)(32) motifs, forming two-dimensional arrays. The short distances between the centroids of the six-membered rings indicate the existence of π-π inter-actions [centroid-centroid distances = 3.6880 (17)-3.7466 (15) Å].
潜在的单席夫碱配体标题化合物C₁₃H₁₀N₄的不对称单元包含两个晶体学独立的分子，A和B。在分子A中，两个环相互扭曲了13.90（18）°。相比之下，分子B中两个环之间的二面角为0.67（19）°。在晶体结构中，分子通过分子间N-H⋯N相互作用经由R₄（4）（32） motif连接，形成二维阵列。六元环质心之间的短距离表明存在π-π相互作用[质心-质心距离 = 3.6880（17）-3.7466（15）Å]。
