Abstract

Employing ethylenediamine (en) as the template, a new two-dimensional (2D) layered lanthanum sulfate [C2N2H10][La2(H2O)4(SO4)4]·2H2O has been hydrothermally synthesized for the first time. Its structure, solved by single-crystal X-ray diffraction analysis, comprises a network of La(1)O10, La(2)O8 polyhedra and SO4 tetrahedra forming one-dimensional ladder-like chains. The chains, in turn, are linked via oxygen atoms forming macroanionic inorganic zigzag layers. The diprotonated amine molecules and the water molecules are located in the apertures of zigzag layers and interact with the inorganic framework through hydrogen bonding.
