In the last twenty years, the reactivity of homoatomic Zintl anions has been
studied. For these investigations seven atom and nine atom Zintl anions have been
reacted with transition metal complexes to yield ligand stabilized,
intermetalloid'' or alloy-like'' cluster anions. Especially the latter two types
of cluster anions exhibit complex, yet not entirely rationalized bonding situations
and geometrical features.

In the first part of the present thesis, novel heteroatomic Zintl anions and a
phenyl-ligated trimetallic cluster anion have been synthesized. In the second part,
the reactivity of a known heteroatomic, tetrahedral Zintl anion toward transition
metal as well as lanthanide complexes was investigated, giving rise to a variety of
ternary intermetalloid cluster anions. In all of the obtained clusters, the sort of
main group element atoms that hold the majority of atoms in the cluster anions seem
to determine the geometrical properties. The electronic situations within the
cluster anions have been elucidated using quantum chemical investigations. These
studies revealed that the cluster anions can be regarded as a Wade-type cluster
anion, alloy-like molecular anions with complicated bonding situations or electron
precise, fullerane-type Zintl anions.

In the latter, magnetic properties are adjustable by the type of incorporated
lanthanide ions.
