摘要：

The ternary potassium telluroargentate(I), K-4[Ag18Te11], was prepared by solvothermal synthesis in ethylenediamine at 160 degrees C. It crystallizes in the cubic space group Fm (3) over barm (no. 225) with the cell parameter a = 18.6589(6) angstrom. The crystal structure can be described as a [Ag18Te11](4-) three-dimensional anionic framework with the voids accommodating potassium cations. Chemical bonding analysis reveals polar covalent Ag-Te bonds and considerable Ag-Ag interactions, which support the complex anionic character of the structure. The compound is thermally stable up to 450 degrees C in an inert atmosphere.
