Title: Materials Data on BaCaI4 by Materials Project

Abstract

BaCaI4 is trigonal omega-derived structured and crystallizes in the monoclinic P2/m space group. The structure is two-dimensional and consists of one BaCaI4 sheet oriented in the (1, 0, 0) direction. Ba2+ is bonded to six I1- atoms to form BaI6 octahedra that share edges with two equivalent BaI6 octahedra and edges with four equivalent CaI6 octahedra. There are four shorter (3.46 Å) and two longer (3.49 Å) Ba–I bond lengths. Ca2+ is bonded to six I1- atoms to form CaI6 octahedra that share edges with two equivalent CaI6 octahedra and edges with four equivalent BaI6 octahedra. There are two shorter (3.19 Å) and four longer (3.21 Å) Ca–I bond lengths. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a 3-coordinate geometry to two equivalent Ba2+ and one Ca2+ atom. In the second I1- site, I1- is bonded in a 3-coordinate geometry to one Ba2+ and two equivalent Ca2+ atoms.
