V(RuNi)2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two V(RuNi)2 clusters. V(1) is bonded in a distorted linear geometry to one Ru(1) and one Ru(2) atom. The V(1)-Ru(1) bond length is 1.91 Å. The V(1)-Ru(2) bond length is 1.01 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 2-coordinate geometry to one V(1) and two equivalent Ni(1) atoms. Both Ru(1)-Ni(1) bond lengths are 1.14 Å. In the second Ru site, Ru(2) is bonded in a single-bond geometry to one V(1) atom. Ni(1) is bonded in a single-bond geometry to one Ru(1) atom.
