The structure described by Sm2B5 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 12-coordinate geometry to two equivalent B(1), two equivalent B(2), two equivalent B(4), three equivalent B(3), and three equivalent B(5) atoms. In the second Sm site, Sm(2) is bonded in a 12-coordinate geometry to two equivalent B(1), two equivalent B(2), two equivalent B(4), three equivalent B(3), and three equivalent B(5) atoms. There are five inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to two equivalent Sm(1), two equivalent Sm(2), one B(3), two equivalent B(2), and two equivalent B(4) atoms. In the second B site, B(2) is bonded in a 9-coordinate geometry to two equivalent Sm(1), two equivalent Sm(2), one B(3), two equivalent B(1), and two equivalent B(4) atoms. In the third B site, B(3) is bonded in a 9-coordinate geometry to three equivalent Sm(1), three equivalent Sm(2), one B(1), one B(2), and one B(3) atom. In the fourth B site, B(4) is bonded in a 9-coordinate geometry to two equivalent Sm(1), two equivalent Sm(2), one B(5), two equivalent B(1), and two equivalent B(2) atoms. In the fifth B site, B(5) is bonded in a 8-coordinate geometry to three equivalent Sm(1), three equivalent Sm(2), one B(4), and one B(5) atom. is represented by the CIF card [CIF]
