The crystal structure described by La3(AgSn)4 crystallizes in the orthorhombic Immm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 12-coordinate geometry to six equivalent Ag(1), two equivalent Sn(1), and four equivalent Sn(2) atoms. In the second La site, La(2) is bonded to eight equivalent Ag(1), two equivalent Sn(1), and four equivalent Sn(2) atoms to form distorted face-sharing LaAg8Sn6 octahedra. Ag(1) is bonded in a 10-coordinate geometry to two equivalent La(2), three equivalent La(1), one Ag(1), one Sn(2), and three equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to one La(2), two equivalent La(1), and six equivalent Ag(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent La(2), four equivalent La(1), two equivalent Ag(1), and one Sn(2) atom. is represented by the CIF file [CIF]
