A facile synthesis of pseudo one-monodimensional ternary molybdenum chalcogenides M2Mo6X6 (X=Se, Te; M=Li, Na,Cs).

This paper describes ion exchange reactions of In2Mo6X6 with alkali iodide and chloride salts at 550C to give M2Mo6X6 and mixed solid solutions In(2-x)M(x)Mo6X6 (M=Li, Na, K, Rb, Cs; X=Se, Te). Furthermore, we show that ion exchange provides a low temperature route to prepare phases which are not stable at high temperature, such as In(2-x)M(x)Mo6Se6 0
