Mn V Ni
VMnNi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two VMnNi clusters. V(1) is bonded in a linear geometry to one Mn(1) and one Ni(1) atom. The V(1)-Mn(1) bond length is 0.22 Å. The V(1)-Ni(1) bond length is 0.25 Å. Mn(1) is bonded in a distorted single-bond geometry to one V(1) atom. Ni(1) is bonded in a distorted single-bond geometry to one V(1) atom.
