Die Kristallstruktur des „Indium-Diiodids“ (InIInIIII4) / The Crystal Structure of “Indium -Diiodide” (InIInIIII4)

Abstract

The crystal structure of In^IIn^IIII₄ (Indium-diiodide) has been determined by single crystals X-ray methods. The compound crystallized with a GaCl₂-type arrangement in the orthorhombic space group Pnna (lattice constants: a = 842.7(3) pm, b = 1096.5(3) pm, c = 1117.3(3) pm). Coordination polyhedra and bond lengths are discussed in comparison with other In iodides.
