The material structure described by Eu2Os3B5 crystallizes in the monoclinic C2 space group. Eu(1) is bonded in a 2-coordinate geometry to two equivalent Os(2), two equivalent B(1), and three equivalent B(3) atoms. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 5-coordinate geometry to one B(1), one B(3), and three equivalent B(2) atoms. In the second Os site, Os(2) is bonded in a 10-coordinate geometry to four equivalent Eu(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 to four equivalent Eu(1) and two equivalent Os(1) atoms to form edge-sharing BEu4Os2 octahedra. In the second B site, B(2) is bonded in a 5-coordinate geometry to one Os(2), three equivalent Os(1), and one B(3) atom. In the third B site, B(3) is bonded in a 8-coordinate geometry to three equivalent Eu(1), one Os(1), two equivalent Os(2), one B(2), and one B(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
