Ag2CdI4 crystallizes in the tetragonal I-42m space group. Ag(1) is bonded to four equivalent I(1) atoms to form AgI4 tetrahedra that share corners with four equivalent Ag(1)I4 tetrahedra and corners with four equivalent Cd(1)I4 tetrahedra. Cd(1) is bonded to four equivalent I(1) atoms to form CdI4 tetrahedra that share corners with eight equivalent Ag(1)I4 tetrahedra. I(1) is bonded in a trigonal non-coplanar geometry to two equivalent Ag(1) and one Cd(1) atom.
