RESUMO
In the title mol-ecule, C23H14N2O2, the atoms in the carbazole unit deviate from planarity [maximum deviation from mean plane = 0.1018â (8)â Å]. The pyrrole ring makes dihedral angles of 4.44â (5), 3.84â (5), 2.18â (5) and 56.44â (5)° with the pyran, fused benzene rings and phenyl ring, respectively. In the crystal, pairs of N-Hâ¯O hydrogen bonds generate R 2 (2)(14) loops and a C-Hâ¯N inter-action is also found. Mol-ecules are further linked by a number of π-π interactions [centroid-centroid distances vary from 3.5702â (5) to 3.7068â (6)â Å], forming a three-dimensional network.
