The structure described by UBr3 crystallizes in the monoclinic P2_1/m space group. U(1) is bonded in a 9-coordinate geometry to three equivalent Br(1), three equivalent Br(2), and three equivalent Br(3) atoms. There are three inequivalent Br sites. In the first Br site, Br(1) is bonded in a trigonal non-coplanar geometry to three equivalent U(1) atoms. In the second Br site, Br(2) is bonded in a trigonal non-coplanar geometry to three equivalent U(1) atoms. In the third Br site, Br(3) is bonded in a trigonal non-coplanar geometry to three equivalent U(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
