The structure described by PrCoNi is Hexagonal Laves-derived structured and crystallizes in the orthorhombic Imma space group. Pr(1) is bonded in a 12-coordinate geometry to six equivalent Co(1) and six equivalent Ni(1) atoms. Co(1) is bonded to six equivalent Pr(1), two equivalent Co(1), and four equivalent Ni(1) atoms to form CoPr6Co2Ni4 cuboctahedra that share corners with eight equivalent Ni(1)Pr6Co4Ni2 cuboctahedra, corners with ten equivalent Co(1)Pr6Co2Ni4 cuboctahedra, edges with six equivalent Co(1)Pr6Co2Ni4 cuboctahedra, faces with six equivalent Co(1)Pr6Co2Ni4 cuboctahedra, and faces with twelve equivalent Ni(1)Pr6Co4Ni2 cuboctahedra. Ni(1) is bonded to six equivalent Pr(1), four equivalent Co(1), and two equivalent Ni(1) atoms to form NiPr6Co4Ni2 cuboctahedra that share corners with eight equivalent Co(1)Pr6Co2Ni4 cuboctahedra, corners with ten equivalent Ni(1)Pr6Co4Ni2 cuboctahedra, edges with six equivalent Ni(1)Pr6Co4Ni2 cuboctahedra, faces with six equivalent Ni(1)Pr6Co4Ni2 cuboctahedra, and faces with twelve equivalent Co(1)Pr6Co2Ni4 cuboctahedra. is represented by the CIF file [CIF]
