The structure described by Eu2Rh5B4 crystallizes in the orthorhombic Fmmm space group. Eu(1) is bonded in a 16-coordinate geometry to two equivalent Rh(3), four equivalent Rh(1), four equivalent Rh(2), and six equivalent B(1) atoms. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a distorted square co-planar geometry to four equivalent Eu(1) and four equivalent B(1) atoms. In the second Rh site, Rh(2) is bonded in a 4-coordinate geometry to four equivalent Eu(1) and four equivalent B(1) atoms. In the third Rh site, Rh(3) is bonded in a distorted square co-planar geometry to four equivalent Eu(1) and four equivalent B(1) atoms. B(1) is bonded in a 5-coordinate geometry to three equivalent Eu(1), one Rh(3), two equivalent Rh(1), and two equivalent Rh(2) atoms. is represented by the CIF card [CIF]
