Symmetry of octa-coordination environment has a substantial influence on dinuclear Tb^III triple-decker single-molecule magnets.

ABSTRACT: Single-molecule magnet (SMM) properties of terbium(iii)-phthalocyaninato and porphyrinato mixed ligand triple-decker complexes, [(TTP)Tb(Pc)Tb(TTP)] (1) and [(Pc)Tb(Pc)Tb(TTP)] type (2), were studied and were compared with those of the Tb^III homoleptic triple-decker complex [(obPc)Tb(obPc)Tb(obPc)] (3) in order to elucidate the relationship between octa-coordination environments and SMM properties (Tb^III = terbium(iii), TTP^2- = tetraphenylporphyrinato, Pc^2- = phthalocyaninato, obPc^2- = 2,3,9,10,16,17,23,24-octabutoxyphthalocyaninato). By combining TTP^2- and Pc^2- with Tb^III ions, it is possible to make three octa-coordination environments: SP-SP, SAP-SP and SAP-SAP sites, where SAP i
