The material structure described by Ag2ZnI4 crystallizes in the orthorhombic Pmn2_1 space group. Ag(1) is bonded to one I(1), one I(2), and two equivalent I(3) atoms to form AgI4 tetrahedra that share corners with four equivalent Ag(1)I4 tetrahedra and corners with four equivalent Zn(1)I4 tetrahedra. Zn(1) is bonded to one I(1), one I(2), and two equivalent I(3) atoms to form ZnI4 tetrahedra that share corners with eight equivalent Ag(1)I4 tetrahedra. There are three inequivalent I sites. In the first I site, I(1) is bonded in a trigonal non-coplanar geometry to two equivalent Ag(1) and one Zn(1) atom. In the second I site, I(2) is bonded in a trigonal non-coplanar geometry to two equivalent Ag(1) and one Zn(1) atom. In the third I site, I(3) is bonded in a trigonal non-coplanar geometry to two equivalent Ag(1) and one Zn(1) atom. is represented by the CIF file [CIF]
