The material described by K is alpha Samarium structured and crystallizes in the trigonal R-3m space group. There are four inequivalent K sites. In the first K site, K(1) is bonded to six equivalent K(1) and six equivalent K(2) atoms to form a mixture of edge, face, and corner-sharing KK12 cuboctahedra. In the second K site, K(2) is bonded to three equivalent K(1) and nine K(2,2) atoms to form a mixture of edge, face, and corner-sharing KK12 cuboctahedra. In the third K site, K(2) is bonded to three equivalent K(1) and nine K(2,2) atoms to form a mixture of edge, face, and corner-sharing KK12 cuboctahedra. In the fourth K site, K(2) is bonded to three equivalent K(1) and nine K(2,2) atoms to form a mixture of edge, face, and corner-sharing KK12 cuboctahedra. is represented by the CIF file [CIF]
