Ni Ni W Cl
WNi2Cl crystallizes in the monoclinic Cm space group. W(1) is bonded in a 12-coordinate geometry to four equivalent W(1), four equivalent Ni(1), and four equivalent Ni(2) atoms. All W(1)-W(1) bond lengths are 2.81 Å. There are a spread of W(1)-Ni(1) bond distances ranging from 2.59-3.11 Å. There are a spread of W(1)-Ni(2) bond distances ranging from 2.59-3.11 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 3-coordinate geometry to four equivalent W(1) and four equivalent Cl(1) atoms. There are a spread of Ni(1)-Cl(1) bond distances ranging from 2.03-2.65 Å. In the second Ni site, Ni(2) is bonded in a 1-coordinate geometry to four equivalent W(1) and three equivalent Cl(1) atoms. There is one shorter (2.44 Å) and two longer (2.73 Å) Ni(2)-Cl(1) bond lengths. Cl(1) is bonded in a 7-coordinate geometry to three equivalent Ni(2) and four equivalent Ni(1) atoms.
