The material described by Cs4Pr6C2I13 crystallizes in the tetragonal I4_1/amd space group. Cs(1) is bonded in a 7-coordinate geometry to one I(1), two equivalent I(4), and four equivalent I(3) atoms. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to one C(1), one I(1), two equivalent I(3), and two equivalent I(4) atoms to form distorted PrCI5 octahedra that share  a cornercorner with one Pr(1)CI5 octahedra, corners with two equivalent Pr(2)C2I5 pentagonal bipyramids, and edges with four equivalent Pr(2)C2I5 pentagonal bipyramids. The corner-sharing octahedra are not tilted. In the second Pr site, Pr(2) is bonded to two equivalent C(1), one I(3), two equivalent I(2), and two equivalent I(4) atoms to form distorted PrC2I5 pentagonal bipyramids that share  a cornercorner with one Pr(1)CI5 octahedra, edges with two equivalent Pr(1)CI5 octahedra, edges with two equivalent Pr(2)C2I5 pentagonal bipyramids, and faces with two equivalent Pr(2)C2I5 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 7°. C(1) is bonded in a 6-coordinate geometry to one Pr(1), four equivalent Pr(2), and one C(1) atom. There are four inequivalent I sites. In the first I site, I(4) is bonded to two equivalent Cs(1), one Pr(1), and two equivalent Pr(2) atoms to form distorted ICs2Pr3 trigonal bipyramids that share corners with three equivalent I(4)Cs2Pr3 trigonal bipyramids,  an edgeedge with one I(4)Cs2Pr3 trigonal bipyramid, and  a faceface with one I(1)Cs4Pr2 octahedra. In the second I site, I(1) is bonded to four equivalent Cs(1) and two equivalent Pr(1) atoms to form face-sharing ICs4Pr2 octahedra. In the third I site, I(2) is bonded in a 2-coordinate geometry to two equivalent Pr(2) atoms. In the fourth I site, I(3) is bonded in a 6-coordinate geometry to four equivalent Cs(1), one Pr(1), and one Pr(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
