A new salt-inclusion compound CsCl·(VOSe2O5)4 showing nearly isolated spin-1/2 chain structure with a typical square lattice

Abstract

A new salt-inclusion compound CsCl·(VOSe₂O₅)₄ was synthesized by the hydrothermal method, showing a linear spin-1/2 chain structure composed of corner-sharing VO₆ octahedra along the c-axis, where such spin-chains are stacked into a regular square lattice on the a–b plane. Magnetic measurements confirm that the title compound does not possess a long-range magnetic ordering down to 2 K, but shows a typical paramagnetic behavior.
