YNiP is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to six equivalent Ni(1) and six equivalent P(1) atoms to form a mixture of face and edge-sharing YNi6P6 cuboctahedra. In the second Y site, Y(2) is bonded to six equivalent Ni(1) and six equivalent P(1) atoms to form a mixture of face and edge-sharing YNi6P6 cuboctahedra. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Y(1), three equivalent Y(2), and three equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to three equivalent Y(1), three equivalent Y(2), and three equivalent Ni(1) atoms.
