Sr Sr Al In
Sr2InAl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Sr2InAl cluster. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one In(1) atom. The Sr(1)-In(1) bond length is 0.54 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one In(1) atom. The Sr(2)-In(1) bond length is 0.50 Å. In(1) is bonded in a distorted single-bond geometry to one Sr(1), one Sr(2), and one Al(1) atom. The In(1)-Al(1) bond length is 0.24 Å. Al(1) is bonded in a single-bond geometry to one In(1) atom.
