| Popis: | A new layered gallium phosphate Ga10(PO4)2(HPO4)12(OH)5⋅2.5N4C6H20⋅4.5H2O was hydrothermally synthesized at 180 °C for 3 days by using triethylenetetramine (teta) as structure-directing agent. Its structure was determined by single-crystal X-ray diffraction with a triclinic cell in the space group P-1 (no 2) with a = 8.4718 ( 1 ) A , b = 18.5915 ( 1 ) A , c = 24.1994 ( 3 ) A , α = 110.538 ( 1 ) ° , β = 93.656 ( 1 ) ° , γ = 93.549 ( 1 ) ° and V = 3547.45 ( 6 ) A 3 . It consists of [Ga10(PO4)2(HPO4)12(OH)5]5− macroanionic sheets composed of infinite chains of GaO4(OH)2 octahedra connected via corner-sharing to PO4 and GaO4 tetrahedra. They contain four-, seven- and nine-membered rings. The inorganic layers are held together through hydrogen bond between the terminal P O bondings, the water molecules and the terminal ammonium groups of the intercalated teta molecules. |
