The structure described by Gd2OsB6 crystallizes in the orthorhombic Pbam space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 17-coordinate geometry to three equivalent Os(1), two equivalent B(2), two equivalent B(3), two equivalent B(4), two equivalent B(5), two equivalent B(6), and four equivalent B(1) atoms. In the second Gd site, Gd(2) is bonded in a 14-coordinate geometry to two equivalent Os(1), two equivalent B(2), two equivalent B(3), two equivalent B(4), two equivalent B(5), and four equivalent B(6) atoms. Os(1) is bonded in a 15-coordinate geometry to two equivalent Gd(2), three equivalent Gd(1), two equivalent B(1), two equivalent B(2), two equivalent B(3), two equivalent B(4), and two equivalent B(5) atoms. There are six inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to four equivalent Gd(1), two equivalent Os(1), one B(1), one B(2), and one B(5) atom. In the second B site, B(2) is bonded in a 9-coordinate geometry to two equivalent Gd(1), two equivalent Gd(2), two equivalent Os(1), one B(1), one B(3), and one B(6) atom. In the third B site, B(3) is bonded in a 9-coordinate geometry to two equivalent Gd(1), two equivalent Gd(2), two equivalent Os(1), one B(2), one B(4), and one B(5) atom. In the fourth B site, B(4) is bonded in a 9-coordinate geometry to two equivalent Gd(1), two equivalent Gd(2), two equivalent Os(1), one B(3), one B(5), and one B(6) atom. In the fifth B site, B(5) is bonded in a 9-coordinate geometry to two equivalent Gd(1), two equivalent Gd(2), two equivalent Os(1), one B(1), one B(3), and one B(4) atom. In the sixth B site, B(6) is bonded in a 9-coordinate geometry to two equivalent Gd(1), four equivalent Gd(2), one B(2), one B(4), and one B(6) atom. is represented by the CIF card [CIF]
