Graphical abstract
A novel three-dimensional (3-D) Dy–Cu heterometallic polymer1contains two distinct units of 1-D Dy–carboxyl belt and Cu–I chain. The two types of 1-D units are further linked via pca ligands to give a heterometallic Dy–Cu framework. The two different types of 1-D building units are rarely observed in the reported heterometallic framework.
