Understanding of multimetallic cluster growth.

ABSTRACT: The elucidation of formation mechanisms is mandatory for understanding and planning of synthetic routes. For (bio-)organic and organometallic compounds, this has long been realized even for very complicated molecules, whereas the formation of ligand-free inorganic molecules has widely remained a black box to date. This is due to poor structural relationships between reactants and products and the lack of structurally related intermediates--due to the comparably high coordination flexibility of involved atoms. Here we report on investigations of the stepwise formation of multimetallic clusters, based on a series of crystal structures and complementary quantum-chemical studies of (Ge2As2)(2-), (Ge7As2)(2-), [Ta@Ge6As4](3-), [Ta@Ge8As4](3-) and [Ta@Ge8As6](3-). The study makes use of efficien
