Mg Ge Mo Mo
MgMo2Ge crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgMo2Ge clusters. Mg(1) is bonded in a single-bond geometry to one Mo(1) and one Ge(1) atom. The Mg(1)-Mo(1) bond length is 1.88 Å. The Mg(1)-Ge(1) bond length is 0.25 Å. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a distorted single-bond geometry to one Mg(1) atom. In the second Mo site, Mo(2) is bonded in a distorted single-bond geometry to one Ge(1) atom. The Mo(2)-Ge(1) bond length is 2.03 Å. Ge(1) is bonded in a single-bond geometry to one Mg(1) and one Mo(2) atom.
