Stepwise assembly of heterometallic 3d–4f chain exhibiting slow magnetic relaxation

The self-assembly of polyalcohol ligand 1,1,1-tris(hydroxymethyl)ethane with Dy(NO3)3·6H2O and Cr3O-Bzo-t-Bu precursor in the presence of triethylamine step-by-step generated a heterometallic 3d–4f chain. Magnetic investigation of the complex indicates typical slow relaxation of the magnetization at low temperature.

A new [Cr2Dy3] cluster-based heterometallic one-dimensional (1D) complex has been prepared via stepwise strategy. AC measurements indicate that complex 1 exhibits slow magnetic relaxation.Figure optionsDownload as PowerPoint slide
