Abstract

The titanyl arsenate NaTiO[AsO4] was synthesized in the form of colourless lath-shaped crystals from arsenic and titanium dioxide in a NaCl/KCl flux at 850 °C. NaTiO[AsO4] crystallizes with the monoclinic low-temperature form LT-CaTiO[SiO4], space group P21/c. The structure was refined from single crystal diffractometer data: a = 6.7170(9), b = 8.7707(12), c = 7.2447(10) Å, β = 114.77(1)°, wR2 = 0.0559, 789 F 2 values, and 74 variables. NaTiO[AsO4] is characterized by a topology common to a wide range of oxide structures of stoichiometry AMOXO4. It consists of parallel chains of trans-corner-sharing TiO6 octahedra, cross-linked by isolated AsO4 tetrahedra.
