Pr2Cr3Co14 crystallizes in the trigonal R-3m space group. Pr(1) is bonded in a 16-coordinate geometry to one Co(3), six equivalent Co(1), and nine equivalent Co(2) atoms. Cr(1) is bonded in a 10-coordinate geometry to two equivalent Co(3), four equivalent Co(1), and four equivalent Co(2) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 12-coordinate geometry to two equivalent Pr(1), two equivalent Cr(1), two equivalent Co(1), two equivalent Co(3), and four equivalent Co(2) atoms. In the second Co site, Co(2) is bonded to three equivalent Pr(1), two equivalent Cr(1), one Co(3), two equivalent Co(2), and four equivalent Co(1) atoms to form a mixture of distorted edge, face, and corner-sharing CoPr3Cr2Co7 cuboctahedra. In the third Co site, Co(3) is bonded in a 14-coordinate geometry to one Pr(1), three equivalent Cr(1), one Co(3), three equivalent Co(2), and six equivalent Co(1) atoms.
