Triethylamine-templated nanocalix Ln12 clusters of diacylhydrazone: crystal structure and magnetic properties

Abstract

Three {Ln12} (Ln = Gd (1), Tb (2), Dy (3)) nanocalix clusters with a novel ligand of N,N'-bis(o-vanillidene)-1H-imidazole-4,5-dicarbohydrazide (H5ovih) were synthesized via the amine-templating strategy. The skeletal structures of these clusters were constructed from three symmetric {Ln4} units via the linkage of three V-type ligands, with a calix shape, which has not been reported previously. Complex 1 exhibited a clear magnetocaloric effect (MCE), whose maximum −ΔSm value reached 36.77 J kg-1 K-1 at 70 kOe and 2.0 K.
