Syntheses, crystal structures, and characterization of two new Tl+-Cu2+-Te6+ oxides: Tl4CuTeO6 and Tl6CuTe2O10

► Two New Tl-Te-Cu-oxides have been synthesized and structurally characterized. ► For Tl4CuTeO6, magnetic measurements indicate a maximum at ∼8 K. ► Low temperature neutron diffraction data confirm no long-range magnetic ordering. ► For Tl6CuTe2O10 magnetic measurements revealed no long-range magnetic ordering.
