Hochdrucksynthese und Strukturverfeinerung von SrVO3, Sr2VO4 und Sr3V2O7 / High-Pressure Synthesis and Structure Refinement of SrVO3, Sr2VO4, and Sr3V2O7

  • Klaus-Jürgen Range , Franz Rau and Ulrich Klement

Single crystals of SrVO3, Sr2VO4 and Sr3V2O7 have been obtained by high-pressure reactions in a modified belt-type apparatus. The crystal structures, refined from diffractometer data, are as follows: SrVO3, perovskite type, Pm3̄m, a = 3.8408(3) Å, R = 0.017, Rw = 0.018, composition from occupancy refinement of oxygen positions SrVO2.93(2); Sr2VO4, K2NiF4 type, I 4/mmm, a = 3.837(1), c = 12.569(1) Å, R = 0.014, Rw = 0.017; Sr3V2O7, Sr3Ti2O7 type, I 4/mmm, a = 3.839(1), c = 20.262(2) Å, R = 0.020, Rw = 0.029.
