Sr La La Sn
SrLa2Sn crystallizes in the triclinic P1 space group. Sr(1) is bonded in a distorted single-bond geometry to two equivalent La(1) and one Sn(1) atom. There is one shorter (3.07 Å) and one longer (4.09 Å) Sr(1)-La(1) bond length. The Sr(1)-Sn(1) bond length is 1.76 Å. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 7-coordinate geometry to two equivalent Sr(1), two equivalent La(1), two equivalent La(2), and one Sn(1) atom. Both La(1)-La(1) bond lengths are 3.83 Å. There is one shorter (2.68 Å) and one longer (3.81 Å) La(1)-La(2) bond length. The La(1)-Sn(1) bond length is 3.41 Å. In the second La site, La(2) is bonded in a 1-coordinate geometry to two equivalent La(1) and one Sn(1) atom. The La(2)-Sn(1) bond length is 2.83 Å. Sn(1) is bonded in a distorted single-bond geometry to one Sr(1), one La(1), and one La(2) atom.
