The material structure described by MgV2Te2O7F2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), one O(4), one O(5), and one O(7) atom. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(2), one O(3), one O(5), one O(6), one F(1), and one F(2) atom to form distorted edge-sharing VO4F2 octahedra.

In the first Te site, Te(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(4), one O(6), and one O(7) atom. In the second Te site, Te(2) is bonded in a distorted rectangular see-saw-like geometry to one O(2), one O(3), one O(5), and one O(7) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mg(1), one V(2), and one Te(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one V(1), one V(2), and one Te(2) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Mg(1), one V(1), and one Te(2) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Mg(1), one V(2), and one Te(1) atom. In the fifth O site, O(5) is bonded in a trigonal non-coplanar geometry to one Mg(1), one V(1), and one Te(2) atom. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one V(1), one V(2), and one Te(1) atom. In the seventh O site, O(7) is bonded in a T-shaped geometry to one Mg(1), one Te(1), and one Te(2) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a water-like geometry to one V(1) and one V(2) atom. In the second F site, F(2) is bonded in a water-like geometry to one V(1) and one V(2) atom. is represented by the CIF card [CIF]
