Abstract
A new propylene-1,3-diammonium gallium phosphate of composition (C 3H12N2)6[Ga12P 16O64] · 4.3 H2O (LUH-1) was obtained by ionothermal synthesis using a deep-eutectic solvent (DES) composed of choline chloride and tetrahydro-2-pyrimidione as reaction medium. The structure-directing agent propylene-1,3-diammonium was generated in situ by the thermally induced decomposition of the amide component of the DES. Single-crystal X-ray structure analysis revealed that LUH-1 is built from macroanionic tetrahedral gallium phosphate layers and layers of interlamellar propylene-1,3-diammonium cations, with the latter exhibiting two-fold disorder. The one-dimensional 12-membered ring channel system is occupied by highly disordered water molecules. As indicated by thermogravimetry and powder X-ray diffraction the water molecules can be desorbed from LUH-1 at ca. 100°C with retention of the layered inorganic-organic hybrid structure. Crystal data for LUH-1: Trigonal system, space group P3̄ c1 (No. 165), Z = 1, a= 12.905(4), c = 18.317(8) Å, T = 297 K.
