The crystal structure described by HoCoO3 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. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 33°. 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 Co(1) atoms. In the second O site, O(2) is bonded to two equivalent Ho(1) and two equivalent Co(1) atoms to form distorted corner-sharing OHo2Co2 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
