The material structure described by BaMgHo(CoO3)2 crystallizes in the orthorhombic Pmmm space group. Ba(1) is bonded to four equivalent O(2), four equivalent O(3), and four equivalent O(4) atoms to form a mixture of distorted corner and face-sharing BaO12 cuboctahedra. Mg(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(3) atoms. Ho(1) is bonded in a distorted square co-planar geometry to four equivalent O(4) atoms. Co(1) is bonded in a square co-planar geometry to one O(1), one O(2), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to two equivalent Mg(1) and two equivalent Co(1) atoms. In the second O site, O(2) is bonded in a linear geometry to four equivalent Ba(1) and two equivalent Co(1) atoms. In the third O site, O(3) is bonded in a T-shaped geometry to two equivalent Ba(1), one Mg(1), and two equivalent Co(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Ho(1) atoms. is represented by the CIF card [CIF]
