Mg Ag Ru
MgRuAg crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgRuAg clusters. Mg(1) is bonded in a distorted single-bond geometry to one Ru(1) and one Ag(1) atom. The Mg(1)-Ru(1) bond length is 1.94 Å. The Mg(1)-Ag(1) bond length is 0.30 Å. Ru(1) is bonded in a single-bond geometry to one Mg(1) atom. Ag(1) is bonded in a single-bond geometry to one Mg(1) atom.
