In the title mol-ecule, C(16)H(11)N(5), the mean planes of the quinoxaline and indazole fragments form a dihedral angle of 10.62 (5)°. In the crystal, weak inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into zigzag chains extending in the [001] direction. The crystal packing also exhibits π-π inter-actions [centroid-centroid distances of 3.7080 (2) and 3.8220 (5) Å], which form stacks of the mol-ecules parallel to the a axis.
在标题分子C(16)H(11)N(5)中，喹喔啉和吲唑片段的平均平面形成10.62 (5)°的二面角。在晶体中，弱分子间N-H⋯N氢键将分子连接成沿[001]方向延伸的锯齿链。晶体堆积还表现出π-π相互作用[质心-质心距离为3.7080 (2) 和3.8220 (5) Å]，形成平行于a轴的分子堆积。
