Abstract

Abstract : A robust, cationic, macrocyclic single-molecule magnet [Cu3 Tb(L Et )] was covalently linked using terephthalate linkers, forming a 1D-polymer that exhibits slow dynamics of the magnetisation. Abstract : Crystallisation of the tetranuclear 3d–4f Single-Molecule Magnet (SMM) [CuII3Tb III (L Et )(NO3 )3 (MeOH)]·MeOH (1 ) with Na2 [tpa] (tpa = terephthalate and H6 L Et is the [3 + 3] imine macrocycle derived from 1, 4-diformyl-2, 3-dihydroxybenzene and 1, 2-diaminoethane) gives a structurally characterised one-dimensional cationic polymer {[CuII3Tb III (L Et )(tpa)(H2 O)3 ](NO3 )·0.5H2 O·0.25MeOH} n (2 ). A comparative study of the static and dynamic magnetic properties of2 and its precursor, 1, is reported.
