La Ni Ni W
LaWNi2 crystallizes in the monoclinic Cm space group. La(1) is bonded in a 9-coordinate geometry to one W(1), four equivalent Ni(1), and four equivalent Ni(2) atoms. The La(1)-W(1) bond length is 3.12 Å. There are a spread of La(1)-Ni(1) bond distances ranging from 2.60-2.93 Å. There are a spread of La(1)-Ni(2) bond distances ranging from 2.14-2.53 Å. W(1) is bonded in a 13-coordinate geometry to one La(1), four equivalent W(1), four equivalent Ni(1), and four equivalent Ni(2) atoms. All W(1)-W(1) bond lengths are 3.09 Å. There are a spread of W(1)-Ni(1) bond distances ranging from 3.05-3.33 Å. There are a spread of W(1)-Ni(2) bond distances ranging from 3.05-3.33 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to four equivalent La(1), four equivalent W(1), and one Ni(2) atom. The Ni(1)-Ni(2) bond length is 2.49 Å. In the second Ni site, Ni(2) is bonded in a 4-coordinate geometry to four equivalent La(1), four equivalent W(1), and one Ni(1) atom.
