High temperature Fe(iii) spin crossover behaviours in three unprecedented FeIII–MII–FeIII (M = Fe, Cd) linear trinuclear complexes†
Abstract
An azo-based ligand of azotetrazolyl-2,7-dihydroxynaphthalene (H3ATD) was used to synthesize three unprecedented FeIII–MII–FeIII (M = Fe, Cd) linear trinuclear complexes with different high temperature spin crossover (SCO) behaviours for the terminal FeIII ions.
