Abstract: The structure of holmium indium molybdenum selenide, Ho_0.76In_1.68Mo₁₅Se₁₉, isotypic with In_2.9Mo₁₅Se₁₉ [Grüttner, Yvon, Chevrel, Potel, Sergent & Seeber (1979). Acta Cryst. B35, 285-292], is characterized by two cluster units Mo₆Seⁱ₈Se^a₆ and Mo₉Seⁱ₁₁Se^a₆ (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 and , respectively. The clusters are interconnected through additional Mo-Se bonds. In the title compound, Ho³⁺ cations replace the trivalent indium observed in In_2.9Mo₁₅Se₁₉, and a deficiency is observed on the monovalent indium site.
