Ligand architecture for triangular metal complexes: a high oxidation state Ni3 cluster with proximal metal arrangement?
Chemical Communications Pub Date: 2020-07-21 DOI: 10.1039/D0CC03816D
Abstract
A new multidentate tetraanionic ligand platform for supporting trinuclear transition metal clusters has been developed. Two trisphenoxide phosphinimide ligands bind three Ni centers in a triangular arrangement. The phosphinimide donors bridge in μ3 fashion and the phenoxides complete a pseudo-square planar coordination sphere around each metal center. Electrochemical studies reveal two pseudo-reversible oxidation events at notably low potentials (?0.80 V and +0.05 V). The one electron oxidized species was characterized structurally, and it is assigned as a NiIII-containing cluster.
