摘　　要：The self-assembly of polyalcohol ligand 1,1,1-tris（hydroxymethyl）ethane with Dy（NO3）3· 6H2 O 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.The self-assembly of polyalcohol ligand 1,1,1-tris（hydroxymethyl）ethane with Dy（NO3）3· 6H2 O and Cr3O-Bzo-t-Bu precursor in the presence of triethylamine step-by-step generated a heterometallic 3d–4f chain.
