Abstract

Abstract{(C2)2O2Dy14}I24 (1) and {(C2)2O2Dy12}I18 (2) were obtained by solid‐state reactions in sealed tantalum containers at a temperature of 1000 °C. {(C2)2O2Dy14}I24 crystallizes in the space group P$\bar1$ with a = 972.97(14) pm, b = 1033.03(13) pm, c = 1677.0(2) pm, α = 101.42(1)°, β = 92.72(1)°, γ = 112.75(1)° and V = 1509.3(3)·106 pm3, Z = 2, and is isotypic with the analogous yttrium and erbium cluster complexes. The tetrameric {(C2)2O2R14}I32 cluster complexes consist of corner‐sharing tetrahedra with endohedral oxygen atoms to which octahedra encapsulating C2 dumbbells are attached on both sides. The tetramers are connected via iodide bridges yielding, e.g., {(C2)2O2Dy14}I24. Connection of the tetramers through common cluster edges leads to the one‐dimensional polymeric cluster complex {(C2)2O2Dy12}I18. It crystallizes in the space group P6/m with a = 2024.18(8) pm, c = 1299.21(4) pm, V = 4610.1(3) × 106 pm3 and Z = 8.
