Na Sr La La
NaSrLa2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a 2-coordinate geometry to one La(1) and one La(2) atom. The Na(1)-La(1) bond length is 3.26 Å. The Na(1)-La(2) bond length is 2.36 Å. Sr(1) is bonded in a 8-coordinate geometry to six equivalent Sr(1), one La(1), and one La(2) atom. There are four shorter (3.69 Å) and two longer (4.08 Å) Sr(1)-Sr(1) bond lengths. The Sr(1)-La(1) bond length is 3.67 Å. The Sr(1)-La(2) bond length is 3.67 Å. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 2-coordinate geometry to one Na(1) and one Sr(1) atom. In the second La site, La(2) is bonded in a distorted single-bond geometry to one Na(1) and one Sr(1) atom.
