Abstract

Amine-templated rare earth sulfates of the compositions: [Ln(2)(H2O)(2)(SO4)(5)][C2N2H10](2), I, with Ln = La, Pr or Nd, [Nd-2(SO4)(4)(H2O)(2)][C4N2H12], II, [Ln(2)(SO4)(4)][C2N2H10], III, with Ln = La or Nd, [La-2(SO4)(4)][C3N2H12], IV and [Ln(2)(SO4)(4)(H2O)(4)][C6N2H14](2)[C2N2H8][SO4][H2O](3), with V, Ln = La, Pr or Nd, have been synthesized under hydrothermal conditions. Both I and II have three-dimensional architectures with I possessing eight-membered apertures surrounding 16-membered apertures, and II having 12 membered apertures. Both III and V have interesting layered structures with LnO(3) layers possessing (6, 3) net topology and the amine located in between the layers. V has a layered structure wherein the SO4 tetrahedra and the LnO(9) polyhedra join together to form (4, 4) net sheets, with two different amines as well as the sulfate ions residing in the interlamellar space.
