AgBiI4 is trigonal omega-derived structured and crystallizes in the orthorhombic Imma space group. Ag(1) is bonded to two equivalent I(2) and four equivalent I(1) atoms to form AgI6 octahedra that share edges with two equivalent Ag(1)I6 octahedra and edges with four equivalent Bi(1)I6 octahedra. Bi(1) is bonded to two equivalent I(1) and four equivalent I(2) atoms to form BiI6 octahedra that share edges with two equivalent Bi(1)I6 octahedra and edges with four equivalent Ag(1)I6 octahedra. There are two inequivalent I sites. In the first I site, I(1) is bonded in a distorted T-shaped geometry to two equivalent Ag(1) and one Bi(1) atom. In the second I site, I(2) is bonded in a distorted T-shaped geometry to one Ag(1) and two equivalent Bi(1) atoms.
