description: Mn2InSbO6 is Corundum-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 pentagonal pyramids that share corners with two SbO6 octahedra, corners with four InO6 pentagonal pyramids, edges with two SbO6 octahedra, and edges with two MnO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 37–44°. There are a spread of Mn–O bond distances ranging from 2.16–2.37 Å. In the second Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 pentagonal pyramids that share corners with two SbO6 octahedra, corners with two equivalent MnO6 pentagonal pyramids, edges with two SbO6 octahedra, an edgeedge with one MnO6 pentagonal pyramid, and edges with three InO6 pentagonal pyramids.
