Abstract

Li2TeS3 and Li2TeSe3 were synthesized by the reaction of stoichiometric amounts of Li, Te and Q (Q = S, Se) in the ratio 2 : 1 : 3. Both products are extremely air and moisture sensitive. The crystal structures were determined by single crystal X-ray diffraction at room temperature. Red Li2TeS3 and metallic black Li2TeSe3 crystallize isotypically in the monoclinic space group P2(1)/c (no. 14) ...
