The crystal structure described by AsI3 is Bismuth triodide structured and crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of six arsenic triiodide molecules. As(1) is bonded in a 3-coordinate geometry to three equivalent I(1) atoms. I(1) is bonded in a single-bond geometry to one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
