PrNiAs is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. Pr(1) is bonded to six equivalent Ni(1) and six equivalent As(1) atoms to form a mixture of face and edge-sharing PrNi6As6 cuboctahedra. Ni(1) is bonded in a distorted trigonal planar geometry to six equivalent Pr(1) and three equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent Ni(1) atoms.
