Materials Data on TbNiP by Materials Project
TbNiP is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded to six equivalent Ni and six equivalent P atoms to form a mixture of edge and face-sharing TbNi6P6 cuboctahedra. All Tb–Ni bond lengths are 2.95 Å. All Tb–P bond lengths are 3.00 Å. In the second Tb site, Tb is bonded to six equivalent Ni and six equivalent P atoms to form a mixture of edge and face-sharing TbNi6P6 cuboctahedra. All Tb–Ni bond lengths are 3.01 Å. All Tb–P bond lengths are 2.95 Å. Ni is bonded in a 3-coordinate geometry to six Tb and three equivalent P atoms. All Ni–P bond lengths are 2.26 Å. P is bonded in a 3-coordinate geometry to six Tb and three equivalent Ni atoms.
