Coordination compounds based on bis-quinolizidine derivatives as ligands are described from the viewpoint of
their spectroscopic and structural properties. The metal ligand ability of C2 substituted sparteines and bis-quinolizidine Noxides
is discussed in order to establish how far the presence of a substituent at α position to the nitrogen atom, involved
in the formation of metal complexes or N-oxide function, influences the course of the complexation reaction and geometry
of the complexes. The results are confronted with theoretical calculations. Potential pharmacological properties of selected
complexes are also determined.
