The material structure described by HoRhAl crystallizes in the orthorhombic Pnma space group. Ho(1) is bonded in a 5-coordinate geometry to five equivalent Rh(1) atoms. Rh(1) is bonded in a 9-coordinate geometry to five equivalent Ho(1) and four equivalent Al(1) atoms. Al(1) is bonded to four equivalent Rh(1) atoms to form a mixture of distorted corner and edge-sharing AlRh4 tetrahedra. is represented by the CIF file [CIF]
