title: Layered Cu7(TeO3)2(SO4)2(OH)6with Diluted Kagomé Net Containing Frustrated Corner-Sharing Triangles.
abstract: The half-spin Kagomé 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 Kagomé lattice in Cu7(TeO3)2(SO4)2(OH)6, showing a 9/16-depleted triangle lattice, where the corner-sharing triangle units [Cu5(OH)6O8] 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.
