The structure described by YbBr2 is Baddeleyite-like structured and crystallizes in the orthorhombic Pbca space group. Yb(1) is bonded to three equivalent Br(1) and four equivalent Br(2) atoms to form a mixture of distorted corner and edge-sharing YbBr7 pentagonal bipyramids. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a trigonal planar geometry to three equivalent Yb(1) atoms. In the second Br site, Br(2) is bonded to four equivalent Yb(1) atoms to form a mixture of corner and edge-sharing BrYb4 tetrahedra. is represented by the CIF card [CIF]
