The asymmetric unit of the title compound, C15H12N2O, contains two independent molecules with different conformations, the phenyl ring and indazole mean plane in the two molecules forming dihedral angles of 50.82 (5) and 89.29 (6)°. In the crystal, weak C—H⋯O and C–H⋯N hydrogen bonds and C—H⋯π interactions consolidate the packing.
In the title compound, C22H18Cl2N2O, the indazole ring system is approximately planar [maximum deviation = 0.031 (2) Å], its mean plane is oriented at 3.17 (4) and 19.34 (4)° with respect to the phenyl and benzene rings. In the crystal, weak C—H...π interactions link the molecules into supramolecular chains running along theb-axis direction.
The asymmetric unit of the title compound, C13H10N2O2, contains two crystallographically independent molecules (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 molecules A and B, respectively. In the crystal, pairs of C—H⋯N hydrogen bonds link the B molecules, forming inversion dimers. These dimers are bridged by the A molecules via C—H⋯O hydrogen bonds, forming sheets parallel to (011). There are also C—H⋯π interactions present, and π–π interactions between neighbouring furan and the indazole rings [centroid–centroid distance = 3.8708 (9) Å] of inversion-related molecules, forming a three-dimensional structure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
