The material structure described by Na3MgCo2SbO6 crystallizes in the triclinic P1 space group. There are three inequivalent Na sites. In the first Na site, Na(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. In the second Na site, Na(2) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and one O(6) atom. In the third Na site, Na(3) is bonded to one O(1), one O(2), one O(3), and one O(6) atom to form distorted NaO4 trigonal pyramids that share  a cornercorner with one Co(1)O4 tetrahedra, corners with two equivalent Mg(1)O4 tetrahedra, and  an edgeedge with one Co(1)O4 tetrahedra. Mg(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form distorted MgO4 tetrahedra that share corners with two equivalent Co(1)O4 tetrahedra and corners with two equivalent Na(3)O4 trigonal pyramids. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(1), one O(3), one O(5), and one O(6) atom to form distorted CoO4 tetrahedra that share corners with two equivalent Mg(1)O4 tetrahedra,  a cornercorner with one Na(3)O4 trigonal pyramid, and  an edgeedge with one Na(3)O4 trigonal pyramid. In the second Co site, Co(2) is bonded in a 3-coordinate geometry to one O(2), one O(4), and one O(6) atom. Sb(1) is bonded in a 3-coordinate geometry to one O(3), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Na(1), one Na(2), one Na(3), one Mg(1), and one Co(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Na(1), one Na(2), one Na(3), one Mg(1), and one Co(2) atom. In the third O site, O(3) is bonded to one Na(1), one Na(2), one Na(3), one Co(1), and one Sb(1) atom to form a mixture of corner and edge-sharing ONa3CoSb trigonal bipyramids. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to one Na(1), one Na(2), one Mg(1), one Co(2), and one Sb(1) atom. In the fifth O site, O(5) is bonded to one Na(1), one Mg(1), one Co(1), and one Sb(1) atom to form a mixture of corner and edge-sharing ONaMgCoSb trigonal pyramids. In the sixth O site, O(6) is bonded in a see-saw-like geometry to one Na(2), one Na(3), one Co(1), and one Co(2) atom. is represented by the CIF file [CIF]
