CoSnNiSn is High Pressure Cadmuum Telluride structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CoSn cluster and one NiSn cluster. In the CoSn cluster, Co(1) is bonded in a 1-coordinate geometry to one Sn(2) atom. The Co(1)-Sn(2) bond length is 1.45 Å. Sn(2) is bonded in a distorted single-bond geometry to one Co(1) atom. In the NiSn cluster, Ni(1) is bonded in a 1-coordinate geometry to one Sn(1) atom. The Ni(1)-Sn(1) bond length is 1.45 Å. Sn(1) is bonded in a distorted single-bond geometry to one Ni(1) atom.
