U(CoB)4 crystallizes in the tetragonal P4_2/nmc space group. U(1) is bonded in a 24-coordinate geometry to twelve equivalent Co(1) and twelve equivalent B(1) atoms. Co(1) is bonded in a 5-coordinate geometry to three equivalent U(1) and five equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent U(1), five equivalent Co(1), and one B(1) atom.
U(CoB)4 crystallizes in the tetragonal P4_2/nmc space group. U(1) is bonded in a 24-coordinate geometry to twelve equivalent Co(1) and twelve equivalent B(1) atoms. There are four shorter (2.81 Å) and eight longer (2.96 Å) U(1)-Co(1) bond lengths. There are eight shorter (2.86 Å) and four longer (2.91 Å) U(1)-B(1) bond lengths. Co(1) is bonded in a 5-coordinate geometry to three equivalent U(1) and five equivalent B(1) atoms. There are four shorter (2.07 Å) and one longer (2.10 Å) Co(1)-B(1) bond length. B(1) is bonded in a 6-coordinate geometry to three equivalent U(1), five equivalent Co(1), and one B(1) atom. The B(1)-B(1) bond length is 1.74 Å.
