SrTa2Mo is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrTa2Mo clusters. Sr(1) is bonded in a single-bond geometry to one Ta(2) atom. The Sr(1)-Ta(2) bond length is 1.21 Å. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a single-bond geometry to one Mo(1) atom. The Ta(1)-Mo(1) bond length is 0.90 Å. In the second Ta site, Ta(2) is bonded in a linear geometry to one Sr(1) and one Mo(1) atom. The Ta(2)-Mo(1) bond length is 0.90 Å. Mo(1) is bonded in a linear geometry to one Ta(1) and one Ta(2) atom.
