TbNiP is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to six equivalent Ni(1) and six equivalent P(1) atoms to form a mixture of face and edge-sharing TbNi6P6 cuboctahedra. In the second Tb site, Tb(2) is bonded to six equivalent Ni(1) and six equivalent P(1) atoms to form a mixture of face and edge-sharing TbNi6P6 cuboctahedra. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1), three equivalent Tb(2), and three equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1), three equivalent Tb(2), and three equivalent Ni(1) atoms.
