The material described by Sm(CrB3)2 crystallizes in the orthorhombic Immm space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent B(1) and twelve equivalent B(2) atoms. Cr(1) is bonded in a 10-coordinate geometry to four equivalent B(1) and six equivalent B(2) atoms. There are two inequivalent B sites. In the first B site, B(2) is bonded in a 9-coordinate geometry to three equivalent Sm(1), three equivalent Cr(1), one B(1), and two equivalent B(2) atoms. In the second B site, B(1) is bonded in a 9-coordinate geometry to two equivalent Sm(1), four equivalent Cr(1), one B(1), and two equivalent B(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
