HoCoO3 crystallizes in the orthorhombic Pnma space group. Ho(1) is bonded to two equivalent O(2) and three equivalent O(1) atoms to form distorted corner-sharing HoO5 trigonal bipyramids. Co(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to three equivalent Ho(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ho(1) and two equivalent Co(1) atoms.
HoCoO3 crystallizes in the orthorhombic Pnma space group. Ho(1) is bonded to two equivalent O(2) and three equivalent O(1) atoms to form distorted corner-sharing HoO5 trigonal bipyramids. Both Ho(1)-O(2) bond lengths are 2.31 Å. There are a spread of Ho(1)-O(1) bond distances ranging from 2.05-2.22 Å. Co(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. There are two shorter (1.92 Å) and two longer (1.95 Å) Co(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to three equivalent Ho(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ho(1) and two equivalent Co(1) atoms.
