The crystal structure of the new complex vanadium oxide Na 6Mg2(VO4)2(V2O 7) was solved from X-ray single-crystal data. The structure contains VO4 tetrahedra and MgO6 octahedra, linked by corners and forming a complex three-dimensional framework. A half of the VO4 tetrahedra are connected only to MgO6 octahedra, whereas the others are corner-sharing, forming V2O7 pyrovanadate groups with statistically random orientations. One unique Mg atom is located at an inversion centre, while the other Mg atom, one unique V atom and five unique O atoms lie on mirror planes.
