Sr Zr Ta
SrZrTa is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrZrTa clusters. Sr(1) is bonded in a linear geometry to one Zr(1) and one Ta(1) atom. The Sr(1)-Zr(1) bond length is 0.46 Å. The Sr(1)-Ta(1) bond length is 0.11 Å. Zr(1) is bonded in a single-bond geometry to one Sr(1) atom. Ta(1) is bonded in a single-bond geometry to one Sr(1) atom.
