  • two halide containing cesium manganese Vanadates synthesis characterization and magnetic properties
    Dalton Transactions, 2018
    Co-Authors: Tiffany Smith M Pellizzeri, Michael A Mcguire, George Chumanov, Colin D Mcmillen, Yimei Wen, Joseph W Kolis
    Abstract:

    Two new halide-containing cesium manganese Vanadates have been synthesized by a high-temperature (580 °C) hydrothermal synthetic method from aqueous brine solutions. One compound, Cs3Mn(VO3)4Cl, (1) was prepared using a mixed cesium hydroxide/chloride mineralizer, and crystallizes in the polar noncentrosymmetric space group Cmm2, with a = 16.7820(8) A, b = 8.4765(4) A, c = 5.7867(3) A. This structure is built from sinusoidal zig-zag (VO3)n chains that run along the b-axis and are coordinated to Mn2+ containing (MnO4Cl) square-pyramidal units that are linked together to form layers. The cesium cations reside between the layers, but also coordinate to the chloride ion, forming a cesium chloride chain that also propagates along the b-axis. The other compound, Cs2Mn(VO3)3F, (2) crystallizes in space group Pbca with a = 7.4286(2) A, b = 15.0175(5) A, c = 19.6957(7) A, and was prepared using a cesium fluoride mineralizer. The structure is comprised of corner sharing octahedral Mn2+ chains, with trans fluoride ligands acting as bridging units, whose ends are capped by (VO3)n Vanadate chains to form slabs. The cesium atoms reside between the manganese Vanadate layers, and also play an integral part in the structure, forming a cesium fluoride chain that runs along the b-axis. Both compounds were characterized by single-crystal X-ray diffraction, powder X-ray diffraction, and single-crystal Raman spectroscopy. Additionally, the magnetic properties of 2 were investigated. Above 50 K, it displays behavior typical of a low dimensional system with antiferromagnetic interactions, as to be expected for linear chains of manganese(ii) within the crystal structure.

  • hydrothermal synthesis and characterization of novel brackebuschite type transition metal Vanadates ba2m vo4 2 oh m v3 mn3 and fe3 with interesting jahn teller and spin liquid behavior
    Inorganic Chemistry, 2015
    Co-Authors: Liurukara D Sanjeewa, V O Garlea, Michael A Mcguire, George Chumanov, Colin D Mcmillen, Joseph W Kolis
    Abstract:

    A new series of transition metal Vanadates, namely, Ba2M(VO4)2(OH) (M = V3+, Mn3+, and Fe3+), was synthesized as large single crystals hydrothermally in 5 M NaOH solution at 580 °C and 1 kbar. This new series of compounds is structurally reminiscent of the brackebuschite mineral type. The structure of Ba2V(VO4)2(OH) is monoclinic in space group P21/m, a = 7.8783(2) A, b = 6.1369(1) A, c = 9.1836(2) A, β = 113.07(3)°, V = 408.51(2) A3. The other structures are similar and consist of one-dimensional trans edge-shared distorted octahedral chains running along the b-axis. The Vanadate groups bridge across edges of their tetrahedra. Structural analysis of the Ba2Mn(VO4)2(OH) analogue yielded a new understanding of the Jahn–Teller effect in this structure type. Raman and infrared spectra were investigated to observe the fundamental Vanadate and hydroxide vibrational modes. Single-crystal temperature-dependent magnetic studies on Ba2V(VO4)2(OH) reveal a broad feature over a wide temperature range with maximum at...
