description: Co3Ni2Te3O16 is beta Vanadium nitride-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Co4+ sites. In the first Co4+ site, Co4+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent NiO6 octahedra, an edgeedge with one NiO6 octahedra, and edges with four TeO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Co–O bond distances ranging from 2.01–2.14 Å. In the second Co4+ site, Co4+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent NiO6 octahedra, an edgeedge with one NiO6 octahedra, edges with two equivalent CoO6 octahedra, and edges with two equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 51–55°. There are a spread of Co–O bond distances ranging from 1.89–1.96 Å. In the third Co4+ site, Co4+ is bonded to six O2- atoms to form distorted CoO6 octahedra that share corners with two equivalent NiO6 octahedra, an edgeedge with one NiO6 octahedra, edges with two equivalent CoO6 octahedra, and edges with two equivalent TeO6 octahedra.
