Materials Data on CuI by Materials Project

Abstract

CuI is Moissanite 9R-like structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are four inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to four I1- atoms to form corner-sharing CuI4 tetrahedra. There are one shorter (2.62 Å) and three longer (2.63 Å) Cu–I bond lengths. In the second Cu1+ site, Cu1+ is bonded to four I1- atoms to form corner-sharing CuI4 tetrahedra. There are three shorter (2.62 Å) and one longer (2.63 Å) Cu–I bond lengths. In the third Cu1+ site, Cu1+ is bonded to four I1- atoms to form corner-sharing CuI4 tetrahedra. There are one shorter (2.62 Å) and three longer (2.63 Å) Cu–I bond lengths. In the fourth Cu1+ site, Cu1+ is bonded to four I1- atoms to form corner-sharing CuI4 tetrahedra. All Cu–I bond lengths are 2.62 Å. There are four inequivalent I1- sites. In the first I1- site, I1- is bonded to four Cu1+ atoms to form corner-sharing ICu4 tetrahedra. In the second I1- site, I1- is bonded to four Cu1+ atoms to form corner-sharing ICu4 tetrahedra. In the third I1- site, I1- is bonded to four Cu1+ atoms to form corner-sharing ICu4 tetrahedra. In the fourth I1- site, I1- is bonded to four Cu1+ atoms to form corner-sharing ICu4 tetrahedra.
