摘要
The novel structure-type Ag2.54Tl2Mo12Se15 (silver thallium molybdenum selenide) is built up of (Mo6Se8Se6a)-Se-i and (Mo9Se11Se6a)-Se-i cluster units in a 1:2 ratio, which are three-dimensionally connected to form the Mo-Se network. The Ag and Tl cations are distributed in several voids within the cluster network. Three of the seven independent Se atoms and one Tl atom lie on sites with 3.. symmetry (Wyckoff sites 2c or 2d).
