Two new iron(III) arsenates K(2)Fe(2)O(AsO(4))(2) (1) and Rb(2)Fe(2)O(AsO(4))(2) (2) have been synthesized and characterized by single-crystal X-ray diffraction, magnetic susceptibilities, and Mossbauer spectroscopy. The two compounds are isostructural and exhibit a sheet structure consisting of infinite slabs of edge-sharing FeO(6) octahedra linked into sheets by AsO(4) tetrahedra, with the alkali-metal

guided‐wave nonlinear process in the material rubidium titanyl arsenate (RTA). Quasi‐phase‐matched frequencydoubling of 874.5 nm light was achieved in a Cs:RTA waveguide, with a normalized conversion efficiency of 225%/W cm2. We also report phase matching characteristics for bulk periodically poled RTA.

The formation conditions and physicochemical properties of binary decavanadates M4Na2V10O28 center dot 10H(2)O (M = K, Rb, NH4), synthesized by crystallization from saturated solutions of the NaVO3-MH2AsO4-H2O systems, were studied by chemical analysis, X-ray powder diffraction, microscopy, thermogravimetry, and IR spectroscopy. To optimize the synthesis conditions of M4Na2V10O28 center dot 10H(2)O, the (1 - x)NaVO3 center dot 2H(2)O center dot xMH(2)AsO(4)-H2O (0.2 <= x <= 0.8) isomolar series method was applied to studying the interaction in the NaVO3-MH2AsO4-H2O systems (M = K, Rb, Cs) at the 0.4 mol/L total molar concentration of NaVO3 and MH2AsO4 in solutions. The studied M4Na2V10O28 center dot 10H(2)O compounds were shown to be isostructural with triclinic crystals (Z = 1, space group P (1) over bar), and their unit cell parameters were estimated.
