Abstract

The crystal structure of a substituted pyranocarbazole alkaloid has been determined by X-ray diffraction method on a single crystal using MoKα radiation. The compound crystallizes in the monoclinic system with the space group P21/c and Z = 4. The unit cell dimensions are a = 5.521(1), b = 15.314(2), c = 19.989(2) Å and β = 93.19(1)°. The structure was solved by direct methods and refined by full-matrix least squares to a final R value of 0.063 with 1551 ‘observed’ reflections. The molecule is not quite planar. The carbazole moiety adopts a slight boat conformation; the dihedral angle between the two six-membered rings is 3.9(2)°. The pyran ring is not planar and makes an angle of 5.2(3)° with the plane of the carbazole moiety. The N(l) – C(19) bond distance is slightly shorter than the single C – N bond value.
