Materials Data on Co2Te3O8 by Materials Project
Abstract
Co2Te3O8 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Co2+ is bonded to six O2- atoms to form a mixture of distorted corner and edge-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 57°. There are a spread of Co–O bond distances ranging from 2.05–2.35 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a see-saw-like geometry to four O2- atoms. There are two shorter (1.91 Å) and two longer (2.12 Å) Te–O bond lengths. In the second Te4+ site, Te4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Te–O bond distances ranging from 1.92–2.71 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Co2+ and two equivalent Te4+ atoms to form distorted edge-sharing OCo2Te2 tetrahedra. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Co2+ and one Te4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Co2+ and two Te4+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry tomore »
