High thermal stability and antiferromagnetic properties of a 3D Mn(II)-organic framework with metal carboxylate chains

A novel three-dimensional metal-organic framework, [Mn2(hfipbb)2(bpy)]n (1) (H2hfipbb = 4,4′-(hexafluoroisopropylidene)bis(benzoic acid), bpy = 4,4′-bipyridine), has been hydrothermally synthesized and structurally characterized. The complex consists of metal carboxylate chains, which are cross-linked to six adjacent chains through organic moieties forming extended three-dimensional networks. Complex 1 exhibits high thermal stability (450 °C) and antiferromagnetic properties.
