A porous 3D heterometal-organic framework containing both lanthanide and high-spin Fe(II) ions

The first porous 3D [Ln-Fe] heterometal-organic frameworks incorporating high-spin Fe(II) ions were structurally characterized with fascinating 1D channels and higher thermal stability: the robust frameworks still keep intact on removing free H2O or adsorbing C2H5OH, and the luminescence of [Eu-Fe] complex displays selective detection of Mg2+.
