PrNiP is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to six equivalent Ni(1) and six equivalent P(1) atoms to form a mixture of edge and face-sharing PrNi6P6 cuboctahedra. In the second Pr site, Pr(2) is bonded to six equivalent Ni(1) and six equivalent P(1) atoms to form a mixture of edge and face-sharing PrNi6P6 cuboctahedra. Ni(1) is bonded in a distorted trigonal planar geometry to three equivalent Pr(1), three equivalent Pr(2), and three equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to three equivalent Pr(1), three equivalent Pr(2), and three equivalent Ni(1) atoms.
