The structure described by K2PrCl5 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Cl(1), two equivalent Cl(2), two equivalent Cl(3), and two equivalent Cl(4) atoms. Pr(1) is bonded to one Cl(2), one Cl(3), one Cl(4), and four equivalent Cl(1) atoms to form distorted edge-sharing PrCl7 pentagonal bipyramids. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to two equivalent K(1) and two equivalent Pr(1) atoms to form distorted ClK2Pr2 trigonal pyramids that share corners with two equivalent Cl(3)K4Pr trigonal bipyramids, corners with two equivalent Cl(4)K4Pr trigonal bipyramids, corners with four equivalent Cl(2)K4Pr trigonal bipyramids, corners with six equivalent Cl(1)K2Pr2 trigonal pyramids,  an edgeedge with one Cl(2)K4Pr trigonal bipyramid, edges with two equivalent Cl(3)K4Pr trigonal bipyramids, edges with two equivalent Cl(4)K4Pr trigonal bipyramids, and  an edgeedge with one Cl(1)K2Pr2 trigonal pyramid. In the second Cl site, Cl(2) is bonded to four equivalent K(1) and one Pr(1) atom to form ClK4Pr trigonal bipyramids that share corners with four equivalent Cl(3)K4Pr trigonal bipyramids, corners with five equivalent Cl(4)K4Pr trigonal bipyramids, corners with eight equivalent Cl(1)K2Pr2 trigonal pyramids,  an edgeedge with one Cl(3)K4Pr trigonal bipyramid, edges with two equivalent Cl(2)K4Pr trigonal bipyramids, edges with two equivalent Cl(4)K4Pr trigonal bipyramids, edges with two equivalent Cl(1)K2Pr2 trigonal pyramids, and  a faceface with one Cl(3)K4Pr trigonal bipyramid. In the third Cl site, Cl(3) is bonded to four equivalent K(1) and one Pr(1) atom to form ClK4Pr trigonal bipyramids that share  a cornercorner with one Cl(4)K4Pr trigonal bipyramid, corners with four equivalent Cl(2)K4Pr trigonal bipyramids, corners with four equivalent Cl(3)K4Pr trigonal bipyramids, corners with four equivalent Cl(1)K2Pr2 trigonal pyramids,  an edgeedge with one Cl(2)K4Pr trigonal bipyramid, edges with four equivalent Cl(4)K4Pr trigonal bipyramids, edges with four equivalent Cl(1)K2Pr2 trigonal pyramids, and  a faceface with one Cl(2)K4Pr trigonal bipyramid. In the fourth Cl site, Cl(4) is bonded to four equivalent K(1) and one Pr(1) atom to form distorted ClK4Pr trigonal bipyramids that share  a cornercorner with one Cl(3)K4Pr trigonal bipyramid, corners with four equivalent Cl(4)K4Pr trigonal bipyramids, corners with five equivalent Cl(2)K4Pr trigonal bipyramids, corners with four equivalent Cl(1)K2Pr2 trigonal pyramids, edges with two equivalent Cl(2)K4Pr trigonal bipyramids, edges with four equivalent Cl(3)K4Pr trigonal bipyramids, and edges with four equivalent Cl(1)K2Pr2 trigonal pyramids. is represented by the CIF card [CIF]
