The crystal structure described by HoRhO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Ho(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. Rh(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles range from 40-44°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Ho(1) and two equivalent Rh(1) atoms. In the second O site, O(2) is bonded to two equivalent Ho(1) and two equivalent Rh(1) atoms to form distorted corner-sharing OHo2Rh2 trigonal pyramids. is represented by the CIF card [CIF]
