Shaping up: The two isomorphous 2D hybrid frameworks {[Ln(tci)(H2O)2]⋅2 H2O}n (Ln=CeIII or PrIII, tciH3=tris(2-carboxyethyl)isocyanurate) were prepared using a highly flexible ligand. The frameworks show a single crystal to single crystal topochemical transformation from a two-dimensional (2D) to three-dimensional (3D) framework and vice versa (see picture) and exhibits selective adsorption properties of H2O over MeOH and EtOH.
