In the title compound, CHNO, the indazole unit is planar to within 0.0171 (10) Å and makes dihedral angles of 6.50 (6) and 6.79 (4)°, respectively, with the nitro and pendant phenyl groups. The conformation of the oxazole ring is best described as an envelope. In the crystal, oblique stacks along the -axis direction are formed by π-π stacking inter-actions between the indazole unit and the pendant phenyl rings of adjacent mol-ecules. The stacks are linked into pairs through C-H⋯O hydrogen bonds. Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H⋯H (36.3%), O⋯H/H⋯O (23.4%), C⋯H/H⋯C (13.4%) and N⋯H/H⋯N (11.4%) inter-actions.
在标题化合物CHNO中，吲唑单元平面度在0.0171(10) Å以内，分别与硝基和侧链苯基形成6.50(6)°和6.79(4)°的二面角。恶唑环的构象最好描述为信封式。在晶体中，沿着轴方向的倾斜堆积是由吲唑单元与相邻分子的侧链苯环之间的π-π堆积相互作用形成的。这些堆积通过C-H⋯O氢键成对连接。 Hirshfeld表面分析和二维指纹图谱表明，对晶体堆积最重要的贡献来自H⋯H（36.3%）、O⋯H/H⋯O（23.4%）、C⋯H/H⋯C（13.4%）和N⋯H/H⋯N（11.4%）相互作用。
