The crystal structure described by MgLa2(CoO3)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form MgO6 octahedra that share faces with two equivalent Co(2)O6 octahedra. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(4), one O(5), one O(6), and two equivalent O(3) atoms. In the second La site, La(2) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), one O(5), one O(6), and two equivalent O(4) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. In the second Co site, Co(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form distorted CoO6 octahedra that share faces with two equivalent Mg(1)O6 octahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one La(1), one La(2), one Co(1), and one Co(2) atom to form a mixture of distorted edge and corner-sharing OLa2MgCo2 trigonal bipyramids. In the second O site, O(2) is bonded to one Mg(1), one La(1), one La(2), one Co(1), and one Co(2) atom to form a mixture of distorted edge and corner-sharing OLa2MgCo2 trigonal bipyramids. In the third O site, O(3) is bonded in a 6-coordinate geometry to one Mg(1), one La(2), two equivalent La(1), one Co(1), and one Co(2) atom. In the fourth O site, O(4) is bonded in a 6-coordinate geometry to one Mg(1), one La(1), two equivalent La(2), one Co(1), and one Co(2) atom. In the fifth O site, O(5) is bonded in a see-saw-like geometry to one Mg(1), one La(1), one La(2), and one Co(2) atom. In the sixth O site, O(6) is bonded in a see-saw-like geometry to one Mg(1), one La(1), one La(2), and one Co(2) atom. is represented by the CIF card [CIF]
