Ni Ni Sb W
WNi2Sb crystallizes in the monoclinic Cm space group. W(1) is bonded in a 1-coordinate geometry to four equivalent Ni(1) and one Sb(1) atom. There are a spread of W(1)-Ni(1) bond distances ranging from 2.94-3.28 Å. The W(1)-Sb(1) bond length is 2.37 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to four equivalent W(1), one Ni(2), and four equivalent Ni(1) atoms. The Ni(1)-Ni(2) bond length is 2.65 Å. All Ni(1)-Ni(1) bond lengths are 2.87 Å. In the second Ni site, Ni(2) is bonded in a 4-coordinate geometry to one Ni(1) and four equivalent Sb(1) atoms. There are a spread of Ni(2)-Sb(1) bond distances ranging from 1.77-2.29 Å. Sb(1) is bonded to one W(1) and four equivalent Ni(2) atoms to form a mixture of distorted corner and edge-sharing SbNi4W square pyramids.
