The structure described by SrMgLaMn2O6 crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(4), one O(5), one O(6), and two equivalent O(3) atoms. Mg(1) is bonded to one O(2), one O(4), one O(5), and one O(6) atom to form MgO4 tetrahedra that share corners with two equivalent Mn(2)O4 tetrahedra and corners with three equivalent Mn(1)O5 trigonal bipyramids. La(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(6) atom to form MnO5 trigonal bipyramids that share corners with three equivalent Mg(1)O4 tetrahedra and corners with three equivalent Mn(2)O4 tetrahedra. In the second Mn site, Mn(2) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form MnO4 tetrahedra that share corners with two equivalent Mg(1)O4 tetrahedra and corners with three equivalent Mn(1)O5 trigonal bipyramids. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Sr(1), one La(1), one Mn(1), and one Mn(2) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Sr(1), one Mg(1), one La(1), one Mn(1), and one Mn(2) atom. In the third O site, O(3) is bonded to two equivalent Sr(1), one La(1), one Mn(1), and one Mn(2) atom to form distorted corner-sharing OSr2LaMn2 trigonal bipyramids. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Sr(1), one Mg(1), one La(1), and one Mn(1) atom. In the fifth O site, O(5) is bonded in a distorted see-saw-like geometry to one Sr(1), one Mg(1), one La(1), and one Mn(2) atom. In the sixth O site, O(6) is bonded in a 4-coordinate geometry to one Sr(1), one Mg(1), one La(1), and one Mn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
