Materials Data on Er(CoB)2 by Materials Project
Er(CoB)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Er3+ is bonded in a body-centered cubic geometry to eight equivalent B3- atoms. All Er–B bond lengths are 2.84 Å. Co+1.50+ is bonded to four equivalent B3- atoms to form a mixture of corner and edge-sharing CoB4 tetrahedra. All Co–B bond lengths are 2.01 Å. B3- is bonded in a 4-coordinate geometry to four equivalent Er3+ and four equivalent Co+1.50+ atoms.
