Abstract

The synthesis and structure of four ternary manganese tellurides are reported. All the title compounds form layered structures wherein MnTe4 tetrahedra are the fundamental building blocks. In two compounds MMnTe2 (M = Li, Na), MnTe4 tetrahedra share three corners in the formation of [MnTe3/3Te]1− layers, the fourth Te is bound to only one Mn and formally bears a negative charge. MnTe4 tetrahedra share both corners and edges in the formation of [Mn4Te6]3− and [Mn4.7Te6]3− layers in Na3Mn4Te6 and Na3Mn4.7Te6, respectively. Structural relationships between these ternary tellurides and oxides will be discussed.
