Sr Sr Mg Mo
Sr2MgMo crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Sr2MgMo cluster. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Mg(1) and one Mo(1) atom. The Sr(1)-Mg(1) bond length is 2.55 Å. The Sr(1)-Mo(1) bond length is 0.52 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Mo(1) atom. The Sr(2)-Mo(1) bond length is 2.56 Å. Mg(1) is bonded in a 1-coordinate geometry to one Sr(1) atom. Mo(1) is bonded in a single-bond geometry to one Sr(1) and one Sr(2) atom.
