The structure described by KPu is alpha Pu-derived structured and crystallizes in the triclinic P-1 space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 7-coordinate geometry to two equivalent K(2), five equivalent K(3), and two equivalent Pu(2) atoms. In the second K site, K(2) is bonded in a 4-coordinate geometry to two equivalent K(1), two equivalent K(3), one Pu(2), one Pu(3), and two equivalent Pu(1) atoms. In the third K site, K(3) is bonded in a 10-coordinate geometry to one K(3), two equivalent K(2), five equivalent K(1), and two equivalent Pu(2) atoms. There are three inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a 4-coordinate geometry to two equivalent K(2), one Pu(1), one Pu(2), and one Pu(3) atom. In the second Pu site, Pu(2) is bonded in a 3-coordinate geometry to one K(2), two equivalent K(1), two equivalent K(3), one Pu(1), and one Pu(3) atom. In the third Pu site, Pu(3) is bonded in a 4-coordinate geometry to one K(2), one Pu(1), one Pu(2), and one Pu(3) atom. is represented by the CIF file [CIF]
