Long-range ferromagnetic ordering in a 3D Cu(II)-tetracarboxylate framework assisted by an unprecedented bidentate μ2-O1,N4 hypoxanthine nucleobase.
The first hypoxanthine (hypH)-assisted 3D Cu(II)-tetracarboxylate framework, {[Cu(2)(hypH)(0.5)(H(2)O)(0.5)(btec)]·1.5H(2)O}(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.
