Accessing low denticity coordination modes of a high denticity tripodal ligand to complete its coordinative repertoire

New coordination complexes of the neutral tripodal tetraamine Me6TREN with tBu(3)Ga or tBu(2)Zn have been synthesised and studied with their molecular structures revealing, for the first time, coordination to metal centres via an eta(1) or eta(2) mode, adding to previously reported eta(3) and eta(4) ligated examples
