Mn Mn Ni Ru
Mn2RuNi crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Mn2RuNi cluster. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a single-bond geometry to one Ru(1) atom. The Mn(1)-Ru(1) bond length is 1.45 Å. In the second Mn site, Mn(2) is bonded in a single-bond geometry to one Ni(1) atom. The Mn(2)-Ni(1) bond length is 0.70 Å. Ru(1) is bonded in a bent 150 degrees geometry to one Mn(1) and one Ni(1) atom. The Ru(1)-Ni(1) bond length is 0.99 Å. Ni(1) is bonded in a bent 120 degrees geometry to one Mn(2) and one Ru(1) atom.
