La La Co Sn
La2CoSn is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La2CoSn clusters. La(1) is bonded in a distorted single-bond geometry to one Co(1) atom. The La(1)-Co(1) bond length is 1.81 Å. Co(1) is bonded in a trigonal non-coplanar geometry to two equivalent La(1) and one Sn(1) atom. The Co(1)-Sn(1) bond length is 0.64 Å. Sn(1) is bonded in a single-bond geometry to one Co(1) atom.
