Synthesis and characterisation of Fe(III) and Co(III) complexes of thiazole-containing thiosemicarbazone ligands
摘要:
Three thiosemicarbazone-based ligands and corresponding Fe(III) and Co(III) coordination complexes have been synthesised and fully characterised. Crystallographic analysis of all ligands and complexes revealed interesting hydrogen bonding and pi-stacking packing arrangements. Magnetic susceptibility and EPR measurements indicate that the Fe(III) complexes are in the low spin state from 4 to 300 K. The complexes exhibit significant solution stability (based on UV/vis and NMR data) and the potential for further functionalisation. Such stability gives solution processability and is ideal for the development of advanced supramolecular materials. (C) 2017 Elsevier B.V. All rights reserved.
