Abstract

Semiconducting binary sulfides are often produced with controlled size and shape by solvothermal synthesis using amine solvents. The versatility of this method, however, has not been extended to dense ternary sulfides that include alkali and transition metal ions, which are renowned for their complex magnetic and electronic properties. We report the solvothermal synthesis of the alkali–transition metal sulfides KFeS₂ and KFe₂S₃. The latter compound is not accessible by direct solid-state synthesis. Magnetic susceptibility measurements indicate antiferromagnetic ordering of KFeS₂ and KFe₂S₃, which contain single and double chains of FeS₄ tetrahedra, respectively. Given the ability to access KFe₂S₃ here, further development of this method may lead to isolation of new functional compounds.
