The molecular configuration of lysergic acid diethylamide (LSD) in crystals of the iodobenzoate has been determined by using x-ray diffraction techniques. The configuration shows strain and steric hindrance and the conformation is fixed. Some of the implications of this for the hallucinogenic activity of LSD are discussed.
