Macrocyclic {3d-4f} SMMs as building blocks for 1D-polymers: selective bridging of 4f ions by use of an O-donor ligand.
Crystallisation of the tetranuclear 3d-4f Single-Molecule Magnet (SMM) [CuTbIII(LEt)(NO3)3(MeOH)]·MeOH (1) with Na2[tpa] (tpa = terephthalate and H6LEtis 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 {[CuTbIII(LEt)(tpa)(H2O)3](NO3)·0.5H2O·0.25MeOH}n(2). A comparative study of the static and dynamic magnetic properties of 2 and its precursor, 1, is reported.
