摘要：

A new ternary molybdenum chalcogenide has been found with composition InxMo15Se19. This compound crystallizes in the hexagonal space group P63/m, and shows both types of blocks Mo6Se8 and Mo9Se11. To our knowledge, this is the first Me9X11 unit ever observed in a material. It presents a homogeneity domain: 2, 9 < x < 3, 4. Substitution of sulphur and tellurium for selenium in In3.3Mo15Se19-yXy (X = S, Te) is possible in the limits 0 < y < 12 and 0 < y < 2 respectively. The new compound becomes a high field superconductor at low temperature. © 1979.
