The material described by KPr3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. K(1) is bonded to twelve Pr(1,1) atoms to form a mixture of face and corner-sharing KPr12 cuboctahedra. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 12-coordinate geometry to four equivalent K(1) and eight equivalent Pr(1) atoms. In the second Pr site, Pr(1) is bonded in a 12-coordinate geometry to four equivalent K(1) and eight equivalent Pr(1) atoms. is represented by the CIF file [CIF]
