Synthesis and crystal structure of two fluorophosphated compounds with different infinite sheets: Sr2Ga(HPO4)(PO4)F2 and Sr2Fe2(HPO4)(PO4)2F2
New compounds, Sr2Ga(HPO4)(PO4)F2 and Sr2Fe2(HPO4)(PO4)2F2, have been prepared by hydrothermal synthesis (700°C, 180 MPa, 24 h) and characterized by single-crystal X-ray diffraction. Sr2Ga(HPO4)(PO4)F2 crystallizes in the monoclinic space group P21/n with a = 8.257(1) Å, b = 7.205(1) Å, c = 13.596(2) Å, β = 108.02(1)°, V = 769.2(2) Å3 and Z = 4 and Sr2Fe2(HPO4)(PO4)2F2 in the triclinic space group P21/n with a = 8.072(1) Å, b = 8.794(1) Å, c = 8.885(1) Å, α = 102.46(1)°, β = 115.95(1)°, γ = 89.95(1)°, V = 550.6(1) Å3 and Z = 2. Structures are both based on different sheets involving corner-linkage between octahedra and tetrahedra. The sheets are linked by Sr2+ cations. Structural relationships exist between the descloizite mineral and the title compounds.
