Materials Data on Zr4NiMo by Materials Project

Zr4MoNi crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are three inequivalent Zr sites. In the first Zr site, Zr is bonded in a 6-coordinate geometry to three equivalent Mo and three equivalent Ni atoms. All Zr–Mo bond lengths are 3.08 Å. All Zr–Ni bond lengths are 2.63 Å. In the second Zr site, Zr is bonded in a 2-coordinate geometry to two equivalent Mo and two equivalent Ni atoms. Both Zr–Mo bond lengths are 3.06 Å. Both Zr–Ni bond lengths are 2.61 Å. In the third Zr site, Zr is bonded in a 2-coordinate geometry to two equivalent Mo atoms. Both Zr–Mo bond lengths are 2.96 Å. Mo is bonded in a 12-coordinate geometry to nine Zr and three equivalent Mo atoms. All Mo–Mo bond lengths are 2.91 Å. Ni is bonded in a 6-coordinate geometry to six Zr atoms.

Materials Data on Zr9NiMo4 by Materials Project

Zr9Mo4Ni crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Zr sites. In the first Zr site, Zr is bonded in a 2-coordinate geometry to four Mo and one Ni atom. There are a spread of Zr–Mo bond distances ranging from 2.91–3.11 Å. The Zr–Ni bond length is 2.62 Å. In the second Zr site, Zr is bonded in a 2-coordinate geometry to two equivalent Mo atoms. Both Zr–Mo bond lengths are 2.97 Å. There are two inequivalent Mo sites. In the first Mo site, Mo is bonded in a 12-coordinate geometry to eight Zr and four Mo atoms. There are two shorter (2.69 Å) and two longer (2.92 Å) Mo–Mo bond lengths. In the second Mo site, Mo is bonded to six equivalent Zr and six equivalent Mo atoms to form face-sharing MoZr6Mo6 cuboctahedra. Ni is bonded in a 6-coordinate geometry to six equivalent Zr atoms.
