Materials Data on U(CoB)4 by Materials Project
U(CoB)4 crystallizes in the tetragonal P4_2/nmc space group. The structure is three-dimensional. U4+ is bonded in a 12-coordinate geometry to twelve equivalent B3- atoms. There are eight shorter (2.86 Å) and four longer (2.91 Å) U–B bond lengths. Co2+ is bonded in a 5-coordinate geometry to five equivalent B3- atoms. There are four shorter (2.07 Å) and one longer (2.10 Å) Co–B bond lengths. B3- is bonded in a 6-coordinate geometry to three equivalent U4+, five equivalent Co2+, and one B3- atom. The B–B bond length is 1.74 Å.
