Sr B Mo Mo
SrMo2B crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrMo2B clusters. Sr(1) is bonded in a 1-coordinate geometry to two equivalent Mo(1) and one B(1) atom. Both Sr(1)-Mo(1) bond lengths are 1.78 Å. The Sr(1)-B(1) bond length is 1.45 Å. Mo(1) is bonded in a 2-coordinate geometry to one Sr(1) and one Mo(1) atom. The Mo(1)-Mo(1) bond length is 0.33 Å. B(1) is bonded in a single-bond geometry to one Sr(1) atom.
