Hexaruthenium cluster complexes of basal edge-bridged square pyramidal metallic skeleton. First efficient synthesis and reactivity studies

An easy one-pot synthetic procedure has led to the first high-yield preparation of hexanuclear cluster complexes of a so far uncommon metallic skeleton, basal edge-bridged square pyramid, directly from the easily available starting materials [Ru3(CO)12] and 2-aminopyridines. This efficient synthesis has opened up the possibility of studying the hitherto unexplored reactivity of these cluster complexes.
