Mixed-metal phosphates K(1.64)Na(0.36)TiFe(PO(4))(3) and K(0.97)Na(1.03)Ti(1.26)Fe(0.74)(PO(4))(3) with a langbeinite framework

Single crystals of the langbeinite-type phosphates K(1.65)Na(0.35)TiFe(PO(4))(3) and K(0.97)Na(1.03)Ti(1.26)Fe(0.74)(PO(4))(3) were grown by crystallization from high-temperature self-fluxes in the system Na(2)O–K(2)O–P(2)O(5)–TiO(2)–Fe(2)O(3) using fixed molar ratios of (Na+K):P = 1.0, Ti:P = 0.20...

description Single crystals of the langbeinite-type phosphates K(1.65)Na(0.35)TiFe(PO(4))(3) and K(0.97)Na(1.03)Ti(1.26)Fe(0.74)(PO(4))(3) were grown by crystallization from high-temperature self-fluxes in the system Na(2)O–K(2)O–P(2)O(5)–TiO(2)–Fe(2)O(3) using fixed molar ratios of (Na+K):P = 1.0, Ti:P = 0.20 and Na:K = 1.0 or 2.0 over the temperature range 1273–953 K. The three-dimensional framework of the two isotypic phosphates are built up from [(Ti/Fe)(2)(PO(4))(3)] structure units containing two mixed [(Ti/Fe)O(6)] octa­hedra (site symmetry 3) connected via three bridging PO(4) tetra­hedra. The potassium and sodium cations share two different sites in the structure that are located in the cavities of the framework. One of these sites has nine and the other twelve surrounding O atoms.
