Y Lu
LuY crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LuY clusters. Lu(1) is bonded in a distorted single-bond geometry to one Y(1) atom. The Lu(1)-Y(1) bond length is 2.57 Å. Y(1) is bonded in a distorted single-bond geometry to one Lu(1) atom.
