The material structure described by Ba2MgTb2Co4O11 crystallizes in the orthorhombic Pmmm space group. Ba(1) is bonded in a 2-coordinate geometry to two equivalent O(4) and four equivalent O(1) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(6) atoms. Tb(1) is bonded in a 10-coordinate geometry to two equivalent O(2), two equivalent O(3), two equivalent O(5), and four equivalent O(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(4), two equivalent O(1), and two equivalent O(3) atoms to form CoO5 square pyramids that share corners with two equivalent Co(2)O6 octahedra and corners with three equivalent Co(1)O5 square pyramids. The corner-sharing octahedral tilt angles are 12°. In the second Co site, Co(2) is bonded to one O(5), one O(6), two equivalent O(1), and two equivalent O(2) atoms to form distorted CoO6 octahedra that share corners with four equivalent Co(2)O6 octahedra and corners with two equivalent Co(1)O5 square pyramids. The corner-sharing octahedral tilt angles range from 0-6°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Tb(1), one Co(1), and one Co(2) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Mg(1), two equivalent Tb(1), and two equivalent Co(2) atoms. In the third O site, O(3) is bonded in a 2-coordinate geometry to two equivalent Tb(1) and two equivalent Co(1) atoms. In the fourth O site, O(4) is bonded to four equivalent Ba(1) and two equivalent Co(1) atoms to form edge-sharing OBa4Co2 octahedra. In the fifth O site, O(5) is bonded in a linear geometry to four equivalent Tb(1) and two equivalent Co(2) atoms. In the sixth O site, O(6) is bonded in a square co-planar geometry to two equivalent Mg(1) and two equivalent Co(2) atoms. is represented by the CIF card [CIF]
