The structure described by PrCo5 crystallizes in the hexagonal P6/mmm space group. Pr(1) is bonded in a 18-coordinate geometry to six equivalent Co(1) and twelve equivalent Co(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent Co(2) atoms. In the second Co site, Co(2) is bonded to four equivalent Pr(1), four equivalent Co(1), and four equivalent Co(2) atoms to form a mixture of corner, edge, and face-sharing CoPr4Co8 cuboctahedra. is represented by the CIF file [CIF]
