The material described by Sm2Ag3Al crystallizes in the monoclinic Cm space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 12-coordinate geometry to three equivalent Ag(1), three equivalent Ag(2), three equivalent Ag(3), and three equivalent Al(1) atoms. In the second Sm site, Sm(2) is bonded in a 12-coordinate geometry to three equivalent Ag(1), three equivalent Ag(2), three equivalent Ag(3), and three equivalent Al(1) atoms. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 10-coordinate geometry to three equivalent Sm(1), three equivalent Sm(2), one Ag(2), two equivalent Ag(3), and one Al(1) atom. In the second Ag site, Ag(2) is bonded in a 10-coordinate geometry to three equivalent Sm(1), three equivalent Sm(2), one Ag(1), one Ag(3), and two equivalent Al(1) atoms. In the third Ag site, Ag(3) is bonded in a 10-coordinate geometry to three equivalent Sm(1), three equivalent Sm(2), one Ag(2), two equivalent Ag(1), and one Al(1) atom. Al(1) is bonded in a 10-coordinate geometry to three equivalent Sm(1), three equivalent Sm(2), one Ag(1), one Ag(3), and two equivalent Ag(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
