Sr Sr In Ga
SrInSrGa is Cubic alpha N2-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrGa clusters and two SrIn clusters. In each SrGa cluster, Sr(2) is bonded in a single-bond geometry to one Ga(1) atom. The Sr(2)-Ga(1) bond length is 0.57 Å. Ga(1) is bonded in a single-bond geometry to one Sr(2) atom. In each SrIn cluster, Sr(1) is bonded in a single-bond geometry to one In(1) atom. The Sr(1)-In(1) bond length is 1.81 Å. In(1) is bonded in a single-bond geometry to one Sr(1) atom.
