Ba Mn Ga
BaMnGa is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BaMnGa cluster. Ba(1) is bonded in a 1-coordinate geometry to one Mn(1) atom. The Ba(1)-Mn(1) bond length is 1.97 Å. Mn(1) is bonded in a distorted bent 120 degrees geometry to one Ba(1) and one Ga(1) atom. The Mn(1)-Ga(1) bond length is 1.53 Å. Ga(1) is bonded in a 1-coordinate geometry to one Mn(1) atom.
