The material structure described by Y is alpha Samarium structured and crystallizes in the trigonal R-3m space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded to six equivalent Y(1) and six equivalent Y(2) atoms to form a mixture of corner, face, and edge-sharing YY12 cuboctahedra. In the second Y site, Y(2) is bonded to three equivalent Y(1) and nine Y(2,2) atoms to form a mixture of corner, face, and edge-sharing YY12 cuboctahedra. In the third Y site, Y(2) is bonded to three equivalent Y(1) and nine Y(2,2) atoms to form a mixture of corner, face, and edge-sharing YY12 cuboctahedra. is represented by the CIF card [CIF]
