Synthesis and characterization of a fluorotitanophosphate (NH4)0.16K1.84[Ti2F2(PO4)2(PO3OH)] with a unique lamella framework.
(NH4)(0.16)K(1.84)[Ti(2)F(2)(PO(4))(2)(PO(3)OH)] (1) has been synthesized under hydrothermal conditions. The structure, the composition, and the thermal stability of 1 were determined by single-crystal X-ray diffraction; inductively coupled plasma-optical emission spectroscopy; IR spectroscopy; elemental analysis; thermogravimetric analysis-differential scanning calorimetry-mass spectrometry; and solid-state (1)H, (31)P, and (19)F NMR, and the phase purity of the bulk sample was checked by powder X-ray diffraction. Complex 1 is a fluorotitanophosphate having a unique lamella framework with both TiO(5)F octahedra and PO(3)OH tetrahedra on the surface of the layer, which leads to two different hydrogen bondings involving both P-OH and Ti-F groups.
