In the third La site, La(3) is bonded in a 9-coordinate geometry to one Sn(3), one Sn(4), one Sn(5), one Sn(6), two equivalent Sn(2), and three equivalent Sn(1) atoms. In the fourth La site, La(4) is bonded in a 8-coordinate geometry to one Sn(4), one Sn(5), one Sn(6), two equivalent Sn(1), and three equivalent Sn(2) atoms. There are six inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to one La(1), one La(2), two equivalent La(4), three equivalent La(3), one Sn(1), one Sn(2), and one Sn(6) atom. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent La(1), two equivalent La(3), three equivalent La(4), one Sn(1), and one Sn(6) atom. In the third Sn site, Sn(3) is bonded in a 8-coordinate geometry to one La(3), two equivalent La(1), three equivalent La(2), one Sn(3), and one Sn(6) atom. In the fourth Sn site, Sn(4) is bonded in a 7-coordinate geometry to one La(1), one La(3), one La(4), two equivalent La(2), and two equivalent Sn(5) atoms. In the fifth Sn site, Sn(5) is bonded in a 7-coordinate geometry to one La(1), one La(3), one La(4), two equivalent La(2), and two equivalent Sn(4) atoms.
