The compound described by Sm2(ReB2)3 is Magnesium tetraboride-derived structured and crystallizes in the monoclinic C2/c space group. Sm(1) is bonded in a 9-coordinate geometry to three equivalent B(1), three equivalent B(3), and four equivalent B(2) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 6-coordinate geometry to one B(3), two equivalent B(2), and three equivalent B(1) atoms. In the second Re site, Re(2) is bonded in a 8-coordinate geometry to two equivalent B(1), two equivalent B(2), and four equivalent B(3) atoms. There are three inequivalent B sites. In the first B site, B(1) is bonded in a 8-coordinate geometry to three equivalent Sm(1), one Re(2), three equivalent Re(1), and one B(3) atom. In the second B site, B(2) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Re(2), two equivalent Re(1), one B(2), and one B(3) atom. In the third B site, B(3) is bonded in a 9-coordinate geometry to three equivalent Sm(1), one Re(1), two equivalent Re(2), one B(1), one B(2), and one B(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
