The compound described by Sr2MgZrVO6 crystallizes in the triclinic P1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. In the second Sr site, Sr(2) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(4), one O(5), and one O(6) atom. Mg(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(5) atom to form MgO5 trigonal bipyramids that share corners with two equivalent Zr(1)O5 trigonal bipyramids and  an edgeedge with one Zr(1)O5 trigonal bipyramid. Zr(1) is bonded to one O(1), one O(2), one O(3), one O(5), and one O(6) atom to form ZrO5 trigonal bipyramids that share corners with two equivalent Mg(1)O5 trigonal bipyramids and  an edgeedge with one Mg(1)O5 trigonal bipyramid. V(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), one O(4), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to one Sr(1), one Sr(2), one Mg(1), and one Zr(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Sr(1), one Sr(2), one Mg(1), one Zr(1), and one V(1) atom. In the third O site, O(3) is bonded to one Sr(1), one Mg(1), one Zr(1), and one V(1) atom to form distorted corner-sharing OSrMgZrV trigonal pyramids. In the fourth O site, O(4) is bonded to one Sr(1), one Sr(2), one Mg(1), and one V(1) atom to form distorted corner-sharing OSr2MgV tetrahedra. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to one Sr(1), one Sr(2), one Mg(1), and one Zr(1) atom. In the sixth O site, O(6) is bonded in a distorted see-saw-like geometry to one Sr(1), one Sr(2), one Zr(1), and one V(1) atom. is represented by the CIF file [CIF]
