N,N′-Bis(di­phenyl­meth­yl)benzene-1,4-di­amine

The complete mol­ecule of the title compound, C₃₂H₂₈N₂, is generated by crystallographic inversion symmetry. The dihedral angles between the central aromatic ring and the pendant adjacent rings are 61.37 (16) and 74.20 (14)°. The N—H group does not participate in hydrogen bonds and there are no aromatic π–π stacking inter­actions in the crystal.

2-[2-(2,6-Di­chloro­benz­yloxy)-2-phenyl­eth­yl]-2H-indazole

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 the b-axis direction.

1-(Furan-2-yl)-2-(2H-indazol-2-yl)ethanone

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.
