Abstract

A series of isostructural 3d–4f coordination clusters (CCs) [Mn4Ln4(OH)6(H2L)2(H3L)2(PhCO2)2(N3)2(MeOH)4]Cl1.6(N3)0.4(NO3)2·2.4H2O·1.6MeOH where Ln = Gd, Tb, Dy, Ho and Er and H5L = bis(2-hydroxyethyl)amino–tris(hydroxymethyl)methane (bis–tris) has been synthesised and structurally characterised. The paramagnetic metal ions within the clusters are weakly antiferromagnetically coupled, with the Tb and Dy compounds displaying slow relaxation of their magnetisation. This is the first report of this versatile ligand being used to target 3d–4f CCs.
