Abstract

The first hypoxanthine (hypH)-assisted 3D Cu^II-tetracarboxylate framework, {[Cu₂(hypH)_0.5(H₂O)_0.5(btec)]·1.5H₂O}_n (btec = 1,2,4,5-benzenetetracarboxylate), was synthesized and exhibits long-range ferromagnetic ordering below 4.5 K, which opens a new window for the applications of nucleobase-based MOFs as magnetic materials.
