Mn Ga Cu Cu
Cu2MnGa is alpha Po structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Cu2MnGa cluster. Mn(1) is bonded in a 2-coordinate geometry to one Cu(1), one Cu(2), and one Ga(1) atom. The Mn(1)-Cu(1) bond length is 0.60 Å. The Mn(1)-Cu(2) bond length is 0.77 Å. The Mn(1)-Ga(1) bond length is 0.87 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted single-bond geometry to one Mn(1) and one Ga(1) atom. The Cu(1)-Ga(1) bond length is 0.77 Å. In the second Cu site, Cu(2) is bonded in a 2-coordinate geometry to one Mn(1) and one Ga(1) atom. The Cu(2)-Ga(1) bond length is 0.60 Å. Ga(1) is bonded in a 3-coordinate geometry to one Mn(1), one Cu(1), and one Cu(2) atom.
