Ba Ba Sr Ag
Ba2SrAg is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ba2SrAg clusters. Ba(1) is bonded in a single-bond geometry to one Ag(1) atom. The Ba(1)-Ag(1) bond length is 1.79 Å. Sr(1) is bonded in a single-bond geometry to one Ag(1) atom. The Sr(1)-Ag(1) bond length is 0.27 Å. Ag(1) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one Sr(1) atom.
