Mg Ga Ru
MgRuGa crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgRuGa clusters. Mg(1) is bonded in a distorted linear geometry to one Ru(1) and one Ga(1) atom. The Mg(1)-Ru(1) bond length is 0.24 Å. The Mg(1)-Ga(1) bond length is 1.23 Å. Ru(1) is bonded in a single-bond geometry to one Mg(1) atom. Ga(1) is bonded in a single-bond geometry to one Mg(1) atom.
