The compound described by Y3Os8B6 crystallizes in the orthorhombic Fmmm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 20-coordinate geometry to two equivalent Y(2), four equivalent Os(1), eight equivalent Os(2), and six equivalent B(2) atoms. In the second Y site, Y(2) is bonded in a 17-coordinate geometry to one Y(1), two equivalent Os(1), four equivalent Os(2), four equivalent Os(3), and six equivalent B(1) atoms. There are three inequivalent Os sites. In the first Os site, Os(1) is bonded in a 4-coordinate geometry to two equivalent Y(1), two equivalent Y(2), two equivalent B(1), and two equivalent B(2) atoms. In the second Os site, Os(2) is bonded in a distorted square co-planar geometry to two equivalent Y(1), two equivalent Y(2), two equivalent B(1), and two equivalent B(2) atoms. In the third Os site, Os(3) is bonded in a 4-coordinate geometry to four equivalent Y(2) and four equivalent B(1) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 8-coordinate geometry to three equivalent Y(2), one Os(1), two equivalent Os(2), and two equivalent Os(3) atoms. In the second B site, B(2) is bonded in a 6-coordinate geometry to three equivalent Y(1), two equivalent Os(1), and four equivalent Os(2) atoms. is represented by the CIF file [CIF]
