Description:
The structure of holmium indium molybdenum selenide, Ho0.76In1.68Mo15Se19, isotypic with In2.9Mo15Se19 [Grüttner, Yvon, Chevrel, Potel, Sergent & Seeber (1979). Acta Cryst. B35, 285–292], is characterized by two cluster units Mo6Se i 8Se a 6 and Mo9Se i 11Se a 6 (where i = inner and a = apical) that are present in a 1:1 ratio. The cluster units are centered at Wyckoff positions 2b and 2c and have point-group symmetry overline{3} and overline{6}, respectively. The clusters are interconnected through additional Mo—Se bonds. In the title compound, Ho3+ cations replace the trivalent indium observed in In2.9Mo15Se19, and a deficiency is observed on the monovalent indium site.
