The crystal structure described by Cs3Cu2I5 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 11-coordinate geometry to one Cu(1), one Cu(2), two equivalent I(1), two equivalent I(2), two equivalent I(3), and three equivalent I(4) atoms. In the second Cs site, Cs(2) is bonded in a 9-coordinate geometry to one Cu(2), one I(1), one I(2), two equivalent I(3), and four equivalent I(4) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted trigonal planar geometry to two equivalent Cs(1), one I(1), and two equivalent I(4) atoms. In the second Cu site, Cu(2) is bonded in a 4-coordinate geometry to one Cs(2), two equivalent Cs(1), one I(2), one I(3), and two equivalent I(4) atoms. There are four inequivalent I sites. In the first I site, I(4) is bonded in a 7-coordinate geometry to two equivalent Cs(2), three equivalent Cs(1), one Cu(1), and one Cu(2) atom. In the second I site, I(1) is bonded in a 6-coordinate geometry to one Cs(2), four equivalent Cs(1), and one Cu(1) atom. In the third I site, I(2) is bonded in a 1-coordinate geometry to one Cs(2), four equivalent Cs(1), and one Cu(2) atom. In the fourth I site, I(3) is bonded in a distorted single-bond geometry to two equivalent Cs(2), four equivalent Cs(1), and one Cu(2) atom. is represented by the CIF file [CIF]
