The structure described by SrYb3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded to twelve Yb(1,1) atoms to form SrYb12 cuboctahedra that share corners with six equivalent Sr(1)Yb12 cuboctahedra; corners with twelve Yb(1,1)Sr4Yb8 cuboctahedra; edges with eighteen Yb(1,1)Sr4Yb8 cuboctahedra; faces with eight equivalent Sr(1)Yb12 cuboctahedra; and faces with twelve Yb(1,1)Sr4Yb8 cuboctahedra. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to four equivalent Sr(1) and eight Yb(1,1) atoms to form YbSr4Yb8 cuboctahedra that share corners with four equivalent Sr(1)Yb12 cuboctahedra; corners with fourteen Yb(1,1)Sr4Yb8 cuboctahedra; edges with six equivalent Sr(1)Yb12 cuboctahedra; edges with twelve Yb(1,1)Sr4Yb8 cuboctahedra; faces with four equivalent Sr(1)Yb12 cuboctahedra; and faces with sixteen Yb(1,1)Sr4Yb8 cuboctahedra. In the second Yb site, Yb(1) is bonded to four equivalent Sr(1) and eight Yb(1,1) atoms to form YbSr4Yb8 cuboctahedra that share corners with four equivalent Sr(1)Yb12 cuboctahedra; corners with fourteen Yb(1,1)Sr4Yb8 cuboctahedra; edges with six equivalent Sr(1)Yb12 cuboctahedra; edges with twelve Yb(1,1)Sr4Yb8 cuboctahedra; faces with four equivalent Sr(1)Yb12 cuboctahedra; and faces with sixteen Yb(1,1)Sr4Yb8 cuboctahedra. is represented by the CIF file [CIF]
