The material described by Pr2(CoNi)5 crystallizes in the orthorhombic Pmmm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 18-coordinate geometry to two equivalent Co(1), four equivalent Co(2), four equivalent Ni(1), and eight equivalent Ni(2) atoms. In the second Pr site, Pr(2) is bonded in a 18-coordinate geometry to two equivalent Co(2), four equivalent Co(1), four equivalent Co(3), and eight equivalent Ni(2) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to one Pr(1), two equivalent Pr(2), two equivalent Co(3), and four equivalent Ni(2) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to one Pr(2), two equivalent Pr(1), two equivalent Ni(1), and four equivalent Ni(2) atoms. In the third Co site, Co(3) is bonded to four equivalent Pr(2), four equivalent Co(1), and four equivalent Ni(2) atoms to form CoPr4Co4Ni4 cuboctahedra that share corners with four equivalent Co(3)Pr4Co4Ni4 cuboctahedra, corners with four equivalent Ni(1)Pr4Co4Ni4 cuboctahedra, corners with eight equivalent Ni(2)Pr4Co5Ni3 cuboctahedra, edges with two equivalent Co(3)Pr4Co4Ni4 cuboctahedra, edges with eight equivalent Ni(2)Pr4Co5Ni3 cuboctahedra, faces with two equivalent Co(3)Pr4Co4Ni4 cuboctahedra, and faces with eight equivalent Ni(2)Pr4Co5Ni3 cuboctahedra. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to four equivalent Pr(1), four equivalent Co(2), and four equivalent Ni(2) atoms to form NiPr4Co4Ni4 cuboctahedra that share corners with four equivalent Co(3)Pr4Co4Ni4 cuboctahedra, corners with four equivalent Ni(1)Pr4Co4Ni4 cuboctahedra, corners with eight equivalent Ni(2)Pr4Co5Ni3 cuboctahedra, edges with two equivalent Ni(1)Pr4Co4Ni4 cuboctahedra, edges with eight equivalent Ni(2)Pr4Co5Ni3 cuboctahedra, faces with two equivalent Ni(1)Pr4Co4Ni4 cuboctahedra, and faces with eight equivalent Ni(2)Pr4Co5Ni3 cuboctahedra. In the second Ni site, Ni(2) is bonded to two equivalent Pr(1), two equivalent Pr(2), one Co(3), two equivalent Co(1), two equivalent Co(2), one Ni(1), and two equivalent Ni(2) atoms to form NiPr4Co5Ni3 cuboctahedra that share corners with two equivalent Co(3)Pr4Co4Ni4 cuboctahedra, corners with two equivalent Ni(1)Pr4Co4Ni4 cuboctahedra, corners with twelve equivalent Ni(2)Pr4Co5Ni3 cuboctahedra, edges with two equivalent Co(3)Pr4Co4Ni4 cuboctahedra, edges with two equivalent Ni(1)Pr4Co4Ni4 cuboctahedra, edges with six equivalent Ni(2)Pr4Co5Ni3 cuboctahedra, faces with two equivalent Co(3)Pr4Co4Ni4 cuboctahedra, faces with two equivalent Ni(1)Pr4Co4Ni4 cuboctahedra, and faces with six equivalent Ni(2)Pr4Co5Ni3 cuboctahedra. is represented by the CIF file [CIF]
