The material described by Tb7PtI12 is trigonal omega-derived structured and crystallizes in the trigonal R-3 space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to one Pt(1), two equivalent I(2), and three equivalent I(1) atoms to form TbPtI5 octahedra that share corners with three equivalent Tb(1)PtI5 octahedra,  an edgeedge with one Tb(2)I6 octahedra, and edges with five equivalent Tb(1)PtI5 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. In the second Tb site, Tb(2) is bonded to six equivalent I(2) atoms to form edge-sharing TbI6 octahedra. Pt(1) is bonded in an octahedral geometry to six equivalent Tb(1) atoms. There are two inequivalent I sites. In the first I site, I(1) is bonded in a distorted T-shaped geometry to three equivalent Tb(1) atoms. In the second I site, I(2) is bonded in a distorted T-shaped geometry to one Tb(2) and two equivalent Tb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
