Abstract

Abstract : A novel thioborate KEu2 In3 B12 S13 features {[In3 B12 S30 ] 32– }∞ polyanionic framework built by B12 S12 clusters and [In6 S6 ] 6+ 12-membered rings. Its structural chemistry, optical/magnetic properties, and theoretical calculations are studied. Abstract : Both borates and sulfides are important inorganic multifunctional materials. Encouraged by this background, thioborates attract considerable interest. However, their investigations are highly hindered by the scarcity of the available ones and the synthetic difficulty of the new ones. Here, we report a new thioborate KEu2 In3 B12 S13 (1 ), which was obtained via a facile solid-state reaction in KI flux. It crystallizes in the trigonal R 3̄ m structure, and the three-dimensional structure features a six InS6 octahedron consolidated B12 icosahedron built {[In3 B12 S12 ] 5− }∞ polyanionic framework and a unique In6 S6 12-membered ring, representing a new type of compound. The B12 S12 cluster is also different from the other known thioborates. The structural chemistry, optical and magnetic properties, as well as theoretical calculations of 1 were systematically studied. This study not only provides a new type of thioborate but also makes a breakthrough in the synthesis of thioborates.
