Na V V Au
NaV2Au is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaV2Au clusters. Na(1) is bonded in a single-bond geometry to two equivalent V(1) and one Au(1) atom. Both Na(1)-V(1) bond lengths are 1.72 Å. The Na(1)-Au(1) bond length is 0.75 Å. V(1) is bonded in a 3-coordinate geometry to one Na(1), one V(1), and one Au(1) atom. The V(1)-V(1) bond length is 0.75 Å. The V(1)-Au(1) bond length is 1.72 Å. Au(1) is bonded in a single-bond geometry to one Na(1) and two equivalent V(1) atoms.
