La6RuNi4Al3Sn crystallizes in the hexagonal P-6m2 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 5-coordinate geometry to one Ni(1), two equivalent Ni(2), and two equivalent Sn(1) atoms. In the second La site, La(2) is bonded in a 9-coordinate geometry to two equivalent Ru(1), four equivalent Ni(2), two equivalent Al(1), and one Sn(1) atom. Ru(1) is bonded in a 9-coordinate geometry to six equivalent La(2) and three equivalent Ni(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent La(1) and six equivalent Al(1) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent La(1), four equivalent La(2), one Ru(1), and two equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to two equivalent La(2), two equivalent Ni(1), and two equivalent Ni(2) atoms. Sn(1) is bonded in a 9-coordinate geometry to three equivalent La(2) and six equivalent La(1) atoms.
