High temperature Fe(<scp>iii</scp>) spin crossover behaviours in three unprecedented Fe^III–M^II–Fe^III(M = Fe, Cd) linear trinuclear complexes

Abstract

An azo-based ligand of azotetrazolyl-2,7-dihydroxynaphthalene (H₃ATD) was used to synthesize three Fe^III–M^II–Fe^III(M = Fe, Cd) linear trinuclear complexes with different high temperature spin crossover (SCO) behaviours for the terminal Fe^IIIions.
