KPr(OCl)4 crystallizes in the orthorhombic P2_12_12 space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent Cl(2) atoms. Pr(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent Cl(1), and two equivalent Cl(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one K(1) and one O(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one K(1), one Pr(1), and one Cl(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted water-like geometry to one Pr(1) and one O(2) atom. In the second Cl site, Cl(2) is bonded in a distorted trigonal planar geometry to two equivalent K(1) and one Pr(1) atom.
