Synthesis, Structure, and Magnetic Properties of A(2)Cu(5)(TeO3)(SO4)(3)(OH)(4) (A = Na, K): The First Compounds with a 1D Kagome Strip Lattice
Two new telluritesulfates A(2)Cu(5)(TeO3)(SO4)(3)(OH)(4) (A = Na, K) have been synthesized by a conventional hydrothermal method. Both compounds feature 1D kagome strip structure built by distorted CuO6 octahedra, which can be regarded as the dimensional reduction of kagome lattice. Magnetic measurements confirmed that the titled compounds possess antiferromagnetic ordering at low temperature, while a field-induced magnetic transition can be observed at critical field. To the best of our knowledge, this is the first time to obtain distorted kagome strip compounds.
