Abstract

The new ternary vanadate Na3MnV2O7.5 has been synthesized by solid state reaction route. Its crystal structure was determined from both powder X-ray diffraction data and high-resolution transmission electron microscopy (HRTEM) analysis. Na3MnV 2O7.5 (P2/c, a = 7.4004(4) , b = 5.6065(3) , c = 17.0876(11) , β = 90.0114(2) °, and Z = 4) crystallizes with a new type of oxygen-deficient perovskite ABO3-δ (δ = 1/2) with the sodium atoms occupying the A site and the vanadium and manganese atoms perfectly ordered in the B site. In Na3MnV2O7.5 the manganese and the vanadium atoms are octahedral and tetrahedral coordinated, respectively. The MnO6 and VO4 polyhedra share edges and form a perovskite 3D-framework with high disorder of the oxygen atoms. HRTEM confirmed this structural model. Na3MnV 2O7.5 was characterized by magnetic susceptibility and specific heat measurements. It is antiferromagnetic with no magnetic ordering down to 2 K.
