Materials Data on AgBiI4 by Materials Project
AgBiI4 is trigonal omega-derived structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Ag1+ is bonded to six I1- atoms to form AgI6 octahedra that share edges with two equivalent AgI6 octahedra and edges with four equivalent BiI6 octahedra. There are four shorter (3.03 Å) and two longer (3.28 Å) Ag–I bond lengths. Bi3+ is bonded to six I1- atoms to form BiI6 octahedra that share edges with two equivalent BiI6 octahedra and edges with four equivalent AgI6 octahedra. There are two shorter (3.10 Å) and four longer (3.14 Å) Bi–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 Ag1+ and one Bi3+ atom. In the second I1- site, I1- is bonded in a 3-coordinate geometry to one Ag1+ and two equivalent Bi3+ atoms.
