The structure described by LiDy2Br5 crystallizes in the monoclinic C2/c space group. Li(1) is bonded to two equivalent Br(3) and four equivalent Br(1) atoms to form corner-sharing LiBr6 octahedra. The corner-sharing octahedral tilt angles are 46°. Dy(1) is bonded in a 7-coordinate geometry to two equivalent Br(1), two 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 4-coordinate geometry to two equivalent Li(1) and two equivalent Dy(1) atoms. In the second Br site, Br(2) is bonded to four equivalent Dy(1) atoms to form distorted BrDy4 trigonal pyramids that share corners with eight equivalent Br(3)LiDy3 tetrahedra, edges with two equivalent Br(3)LiDy3 tetrahedra, and edges with two equivalent Br(2)Dy4 trigonal pyramids. In the third Br site, Br(3) is bonded to one Li(1) and three equivalent Dy(1) atoms to form distorted BrLiDy3 tetrahedra that share corners with three equivalent Br(3)LiDy3 tetrahedra, corners with four equivalent Br(2)Dy4 trigonal pyramids, edges with two equivalent Br(3)LiDy3 tetrahedra, and  an edgeedge with one Br(2)Dy4 trigonal pyramid. is represented by the Crystallographic Information File (CIF) [CIF]
