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.
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 is one shorter (3.93 Å) and one longer (4.09 Å) K(1)-U(1) bond length. There is one shorter (3.89 Å) and one longer (4.02 Å) K(1)-U(2) bond length. There is one shorter (4.12 Å) and one longer (4.17 Å) K(1)-U(3) bond length. 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. There are two shorter (2.81 Å) and one longer (2.82 Å) U(3)-U(1) bond length. There are a spread of U(3)-U(2) bond distances ranging from 2.80-2.83 Å. 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. There is one shorter (2.80 Å) and two longer (2.82 Å) U(1)-U(2) bond lengths. 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.
