Abstract
Mg1VO2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded to five O2- atoms to form MgO5 square pyramids that share corners with six VO6 octahedra, edges with three VO6 octahedra, edges with two equivalent MgO5 square pyramids, and a faceface with one VO6 octahedra. The corner-sharing octahedra tilt angles range from 1–49°. There are a spread of Mg–O bond distances ranging from 2.01–2.20 Å. In the second Mg2+ site, Mg2+ is bonded to five O2- atoms to form MgO5 square pyramids that share corners with six VO6 octahedra, edges with three VO6 octahedra, edges with two equivalent MgO5 square pyramids, and a faceface with one VO6 octahedra. The corner-sharing octahedra tilt angles range from 1–49°. There are a spread of Mg–O bond distances ranging from 2.01–2.20 Å. In the third Mg2+ site, Mg2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Mg–O bond distances ranging from 2.08–2.16 Å. In the fourth Mg2+ site, Mg2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Mg–O bond distances ranging frommore »
