The crystal structure described by KU3 is Magnesium tetraboride-like structured and crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 6-coordinate geometry to two equivalent U(1), two equivalent U(2), and two equivalent U(3) atoms. There are three inequivalent U sites. In the first U site, U(3) is bonded in a 8-coordinate geometry to two equivalent K(1), three equivalent U(1), and three equivalent U(2) atoms. In the second U site, U(1) is bonded in a 8-coordinate geometry to two equivalent K(1), three equivalent U(2), and three equivalent U(3) atoms. In the third U site, U(2) is bonded in a 8-coordinate geometry to two equivalent K(1), three equivalent U(1), and three equivalent U(3) atoms. is represented by the CIF file [CIF]
