摘要

通过水热法合成了一种新的含盐化合物 CsCl-(VOSe2O5)4，该化合物呈现出线性自旋-1/2 链结构，由沿 c 轴的角共享 VO6 八面体组成，这些自旋链在 a-b 平面上堆叠成规则的方形晶格。磁性测量结果证实，标题化合物在 2 K 以下不具有长程磁有序性，而是表现出典型的顺磁性。

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

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.
