The crystal structure described by HI1 is alpha carbon monoxide-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of eight hydriodic acid molecules. H(1,2,3,4,5,6,7,8) is bonded in a single-bond geometry to one I(1,2,3,4,5,6,7,8) atom. I(1,2,3,4,5,6,7,8) is bonded in a single-bond geometry to one H(1,2,3,4,5,6,7,8) atom. is represented by the Crystallographic Information File (CIF) [CIF]
