Zn5(Rh2B)4 crystallizes in the orthorhombic Cmmm space group. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to four equivalent Zn(2) and four equivalent B(1) atoms. In the second Rh site, Rh(2) is bonded in a distorted body-centered cubic geometry to two equivalent Zn(1), two equivalent Zn(2), two equivalent Zn(3), and two equivalent B(1) atoms. In the third Rh site, Rh(3) is bonded in a distorted body-centered cubic geometry to four equivalent Zn(1) and four equivalent B(1) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 8-coordinate geometry to four equivalent Rh(2) and four equivalent Rh(3) atoms. In the second Zn site, Zn(2) is bonded in a 11-coordinate geometry to four equivalent Rh(1), four equivalent Rh(2), one Zn(2), and two equivalent B(1) atoms. In the third Zn site, Zn(3) is bonded in a body-centered cubic geometry to eight equivalent Rh(2) atoms. B(1) is bonded in a 6-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), two equivalent Rh(3), and one Zn(2) atom.
