1-(Furan-2-yl)-2-(2H-indazol-2-yl)ethanone.
The asymmetric unit of the title compound, C13H10N2O2, contains two crystallographically independent mol-ecules (A and B). The indazole ring systems are approximately planar [maximum deviations = 0.0037 (15) and -0.0198 (15) Å], and their mean planes are oriented at 80.10 (5) and 65.97 (4)° with respect to the furan rings in mol-ecules A and B, respectively. In the crystal, pairs of C-H⋯N hydrogen bonds link the B mol-ecules, forming inversion dimers. These dimers are bridged by the A mol-ecules via C-H⋯O hydrogen bonds, forming sheets parallel to (011). There are also C-H⋯π inter-actions present, and π-π inter-actions between neighbouring furan and the indazole rings [centroid-centroid distance = 3.8708 (9) Å] of inversion-related mol-ecules, forming a three-dimensional structure.
