The material structure described by PrCo3 crystallizes in the trigonal R-3m space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 12-coordinate geometry to three equivalent Co(3) and nine equivalent Co(1) atoms. In the second Pr site, Pr(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 Pr(2), three equivalent Pr(1), one Co(3), two equivalent Co(2), and four equivalent Co(1) atoms to form CoPr5Co7 cuboctahedra that share corners with two equivalent Co(3)Pr6Co6 cuboctahedra, corners with fifteen equivalent Co(1)Pr5Co7 cuboctahedra, edges with eight equivalent Co(1)Pr5Co7 cuboctahedra, faces with three equivalent Co(3)Pr6Co6 cuboctahedra, and faces with eleven equivalent Co(1)Pr5Co7 cuboctahedra. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Pr(2) and six equivalent Co(1) atoms. In the third Co site, Co(3) is bonded to six equivalent Pr(1) and six equivalent Co(1) atoms to form CoPr6Co6 cuboctahedra that share corners with twelve equivalent Co(1)Pr5Co7 cuboctahedra, edges with six equivalent Co(3)Pr6Co6 cuboctahedra, and faces with eighteen equivalent Co(1)Pr5Co7 cuboctahedra. is represented by the CIF file [CIF]
