ABSTRACT
In view of the observed effect, the potential mode of action, and the structural similarity to certain neurotransmitters, it is recommended to divide hallucinogenic drugs into psychotomimetics and deliriants. From drugs with a secondary or tertiary amino function no complexes could be isolated, which was shown by examinations of the psychotomimetic DMT and the reference substance gramine. Despite the numerous methods used, it was not possible to obtain complexes with Mn, Fe, Co, Ni, Cu, or Zn as solids, which can be explained by the reduced basicity of the nitrogen or by steric effects. Whereas in primary amines complexes are predominantly formed at the nitrogen atom, the tertiary amines only show a weak correlation between the Eu atom and the N atom. Metal complexes of other hallucinogenic drugs, especially those of the deliriant type, have hardly been commented on.
