The material described by YbCo3 crystallizes in the trigonal R-3m space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 12-coordinate geometry to three equivalent Co(3) and nine equivalent Co(1) atoms. In the second Yb site, Yb(2) is bonded in a 18-coordinate geometry to six equivalent Co(2) and twelve equivalent Co(1) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent Yb(2), three equivalent Yb(1), one Co(3), two equivalent Co(2), and four equivalent Co(1) atoms to form CoYb5Co7 cuboctahedra that share corners with two equivalent Co(3)Yb6Co6 cuboctahedra, corners with fifteen equivalent Co(1)Yb5Co7 cuboctahedra, edges with eight equivalent Co(1)Yb5Co7 cuboctahedra, faces with three equivalent Co(3)Yb6Co6 cuboctahedra, and faces with eleven equivalent Co(1)Yb5Co7 cuboctahedra. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Yb(2) and six equivalent Co(1) atoms. In the third Co site, Co(3) is bonded to six equivalent Yb(1) and six equivalent Co(1) atoms to form CoYb6Co6 cuboctahedra that share corners with twelve equivalent Co(1)Yb5Co7 cuboctahedra, edges with six equivalent Co(3)Yb6Co6 cuboctahedra, and faces with eighteen equivalent Co(1)Yb5Co7 cuboctahedra. is represented by the CIF file [CIF]
