La Mn Sn Sn
LaMnSn2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaMnSn2 clusters. La(1) is bonded in a distorted single-bond geometry to one Mn(1) and two equivalent Sn(1) atoms. The La(1)-Mn(1) bond length is 1.37 Å. Both La(1)-Sn(1) bond lengths are 2.02 Å. Mn(1) is bonded in a distorted single-bond geometry to one La(1) and two equivalent Sn(1) atoms. Both Mn(1)-Sn(1) bond lengths are 2.02 Å. Sn(1) is bonded in a 3-coordinate geometry to one La(1), one Mn(1), and one Sn(1) atom. The Sn(1)-Sn(1) bond length is 1.37 Å.
