[Fe2(C10O8H2)]: An antiferromagnetic 3D iron(ii) carboxylate built from ferromagnetic edge-sharing octahedral chains (MIL-62)

The first three-dimensional iron(II) tetracarboxylate is built from the connection of chains of edge-sharing Fe(II) octahedra by 1,2,4,5-benzenetetracarboxylates; magnetic measurements show an antiferromagnetic coupling of ferromagnetic chains below TN = 25(1) K.
