A new sodium- and manganese-based trivanadate NaMn2V3O10: synthesis, structural and magnetic insights

Abstract : Single crystals of the new compound, NaMn2V3O10, were grown by conventional solid-state reaction. The crystal structure of the synthesized sample was determined using single-crystal X-ray diffraction data. NaMn2V3O10 crystallizes in the tri-clinic system with space group P-1 and cell parameters a = 6.854 (2) angstrom, b = 6.877 (2) angstrom, c = 9.716 (2) angstrom, a = 100.604 (1)degrees, beta = 104.169 (1)degrees, and gamma = 101.390 (1)degrees. The structure of this vanadate built up from the connection of V3O10 groups and MnO6 octahedra via corners leading to an open three-dimensional framework delimiting tunnels along [001] direction, where the Na+ cations are localized. The powder of NaMn2V3O10 was prepared by Pechini method. The magnetic measurement has been evidenced by Curie-Weiss behavior above 4.5 K with theta = - 25.46 K demonstrating the occurrence of predominant antiferromagnetic interactions between Mn2+ cations.
