Abstract

An x-ray structural investigation (diffractometer, Cu, 1001 reflections, direct method, MLS in the anisotropic approximation to R=0.066), of the alkaloid incanine has been performed. The crystals are rhombic, a=10.07, b=16.20, c=14.04 Å, space group P212121, z=4. The conformation of the backbone of the macrocycle in incanine practically coincides with those in fulvine and axillarine.
