Tantalum(v) complexes of an amine triphenolate ligand: a dramatic difference in reactivity between the two labile positionsElectronic supplementary information (ESI) available: synthetic and spectroscopic data for all complexes. See http://www.rsc.org/suppdata/dt/b2/b206759e/

Abstract

A tetradentate trianionic amine triphenolate ligand leads to octahedral Ta(V) complexes of Cs-symmetry, in which the two labile positions that are in cis geometry exhibit a dramatic difference in reactivity, the position trans to a phenoxy group being the active one.
