Ni Pt W W
W2PtNi crystallizes in the monoclinic Cm space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to one Pt(1) and one Ni(1) atom. The W(1)-Pt(1) bond length is 3.30 Å. The W(1)-Ni(1) bond length is 0.93 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Pt(1) and one Ni(1) atom. The W(2)-Pt(1) bond length is 3.30 Å. The W(2)-Ni(1) bond length is 1.58 Å. Pt(1) is bonded to one W(1), one W(2), and six equivalent Pt(1) atoms to form a mixture of edge and corner-sharing PtPt6W2 hexagonal bipyramids. All Pt(1)-Pt(1) bond lengths are 2.77 Å. Ni(1) is bonded in a linear geometry to one W(1) and one W(2) atom.
