Na Li La Sn
NaLiLaSn crystallizes in the trigonal R3m space group. Na(1) is bonded in a distorted linear geometry to one La(1) and one Sn(1) atom. The Na(1)-La(1) bond length is 2.14 Å. The Na(1)-Sn(1) bond length is 2.14 Å. Li(1) is bonded in a distorted single-bond geometry to one La(1) atom. The Li(1)-La(1) bond length is 2.14 Å. La(1) is bonded to one Na(1), one Li(1), and three equivalent Sn(1) atoms to form LaNaLiSn3 trigonal bipyramids that share corners with six equivalent La(1)NaLiSn3 trigonal bipyramids and  a cornercorner with one Sn(1)NaLa3 trigonal pyramid. All La(1)-Sn(1) bond lengths are 2.99 Å. Sn(1) is bonded to one Na(1) and three equivalent La(1) atoms to form distorted SnNaLa3 trigonal pyramids that share  a cornercorner with one La(1)NaLiSn3 trigonal bipyramid and corners with six equivalent Sn(1)NaLa3 trigonal pyramids.
