Mg Mg Cr Ru
MgCrMgRu crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgCr cluster and one MgRu cluster. In the MgCr cluster, Mg(1) is bonded in a single-bond geometry to one Cr(1) atom. The Mg(1)-Cr(1) bond length is 1.21 Å. Cr(1) is bonded in a 1-coordinate geometry to one Mg(1) atom. In the MgRu cluster, Mg(2) is bonded in a single-bond geometry to one Ru(1) atom. The Mg(2)-Ru(1) bond length is 1.21 Å. Ru(1) is bonded in a distorted single-bond geometry to one Mg(2) atom.
