## Abstract A series of 2,6βdiacylpyridine ligand precursors 5aβdΒ·HCl with different tether lengths between the carboxyl and pyridine moiety was prepared and converted into the correspondig trinuclear Fe~3~(ΞΌ~3~βO) complexes 8aβd and 10. Under slow precipitation conditions a tetranuclear complex 9
