Mn Ga Ni Ni
Ni2MnGa crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ni2MnGa cluster. Mn(1) is bonded in a single-bond geometry to one Ni(1) atom. The Mn(1)-Ni(1) bond length is 0.44 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a single-bond geometry to one Mn(1) and one Ga(1) atom. The Ni(1)-Ga(1) bond length is 1.55 Å. In the second Ni site, Ni(2) is bonded in a single-bond geometry to one Ga(1) atom. The Ni(2)-Ga(1) bond length is 1.18 Å. Ga(1) is bonded in a bent 150 degrees geometry to one Ni(1) and one Ni(2) atom.
