7-Methyl-1-phenyl-1,10-dihydropyrazolo[3,4-a]carbazole

Abstract

In the title molecule, C20H15N3, the atoms in the carbazole unit deviate from planarity [maximum deviation from mean plane = 0.1082 (15) Å]. The pyrrole ring makes dihedral angles of 3.17 (8)/4.10 (9), 7.20 (9) and 44.62 (9)° with the fused benzene, pyrazole and phenyl rings, respectively. In the crystal, molecules are linked via N - H⋯N hydrogen bonds, forming an infinite chain along [010]. Molecules are further linked by nine π-π [centroid-centroid distances vary from 3.6864 (11) to 3.9802 (11) Å] and one C - H⋯π interaction, forming a three-dimensional network.
