Sr Ni Sn Sn
SrNiSn2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrNiSn2 cluster. Sr(1) is bonded in a distorted single-bond geometry to one Ni(1) and one Sn(2) atom. The Sr(1)-Ni(1) bond length is 0.87 Å. The Sr(1)-Sn(2) bond length is 2.39 Å. Ni(1) is bonded in a distorted single-bond geometry to one Sr(1) and one Sn(1) atom. The Ni(1)-Sn(1) bond length is 1.53 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a single-bond geometry to one Ni(1) atom. In the second Sn site, Sn(2) is bonded in a single-bond geometry to one Sr(1) atom.
