Materials Data on Co(BO2)2 by Materials Project
CoB2O4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with twelve equivalent BO4 tetrahedra and edges with two equivalent CoO6 octahedra. There are a spread of Co–O bond distances ranging from 2.09–2.28 Å. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with six equivalent CoO6 octahedra, corners with two equivalent BO4 tetrahedra, and an edgeedge with one BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 43–64°. There are a spread of B–O bond distances ranging from 1.45–1.54 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Co2+ and two equivalent B3+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Co2+ and two equivalent B3+ atoms.
