Crystal structure of 4-(4b,8a-di­hydro-9H-pyrido[3,4-b]indol-1-yl)-7-methyl-2H-chromen-2-one

The title compound, C(21)H(14)N(2)O(2), was prepared by Pictet–Spengler cyclization of tryptamine and 4-formyl coumarin. In the mol­ecule, the dihedral angle between the mean planes of the coumarin and β-carboline ring systems is 63.8 (2)°. In the crystal, mol­ecules are linked via N—H⋯N hydrogen bo...

Descripción
Sumario:The title compound, C(21)H(14)N(2)O(2), was prepared by Pictet–Spengler cyclization of tryptamine and 4-formyl coumarin. In the mol­ecule, the dihedral angle between the mean planes of the coumarin and β-carboline ring systems is 63.8 (2)°. In the crystal, mol­ecules are linked via N—H⋯N hydrogen bonds, forming chains along the b-axis direction. Within the chains, there are a number of offset π–π inter­actions present [shortest inter­centroid distance = 3.457 (2) Å].
