半自旋Kagome反铁磁体由于其固有的阻挫和量子涨落而成为实现量子自旋液态最有希望的候选者之一。寻找具有新颖自旋拓扑结构的量子自旋液体的候选者仍然是一个挑战。本文报道了一种新的稀释Kagome晶格结构，它是一个9/16耗尽的三角形晶格，其中角共享三角形单元[Cu-5（OH）（6）O-8]被CuO 2（OH）（2）隔开.磁性测量表明，标题化合物不显示长程反铁磁有序低至2 K，表明与f > 19强自旋挫折。
The half-spin Kagome antiferromagnet is one of the most promising candidates for the realization of a quantum spin liquid state because of its inherent frustration and quantum fluctuations. The search for candidates for quantum spin liquids with novel spin topologies is still a challenge. Herein, we report a new diluted Kagome lattice in Cu-7(TeO3)(2)(SO4)(2)(OH)(6), showing a 9/16-depleted triangle lattice, where the corner-sharing triangle units [Cu-5(OH)(6)O-8] are separated by CuO2(OH)(2). Magnetic measurements show that the title compound does not exhibit long-range antiferromagnetic order down to 2 K, suggesting strong spin frustration with f > 19.
