The structure described by ErOsB4 crystallizes in the orthorhombic Pbam space group. Er(1) is bonded in a 18-coordinate geometry to four equivalent Os(1), two equivalent B(3), four equivalent B(1), four equivalent B(2), and four equivalent B(4) atoms. Os(1) is bonded in a 15-coordinate geometry to four equivalent Er(1), one Os(1), two equivalent B(1), two equivalent B(2), two equivalent B(4), and four equivalent B(3) atoms. There are four inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to four equivalent Er(1), two equivalent Os(1), one B(2), and two equivalent B(4) atoms. In the second B site, B(2) is bonded in a 9-coordinate geometry to four equivalent Er(1), two equivalent Os(1), one B(1), one B(2), and one B(3) atom. In the third B site, B(3) is bonded in a 9-coordinate geometry to two equivalent Er(1), four equivalent Os(1), one B(2), one B(3), and one B(4) atom. In the fourth B site, B(4) is bonded in a 9-coordinate geometry to four equivalent Er(1), two equivalent Os(1), one B(3), and two equivalent B(1) atoms. is represented by the CIF card [CIF]
