Materials Data on Tl(CoSe)2 by Materials Project

TlCo2Se2 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Co+1.50+ is bonded to four equivalent Se2- atoms to form a mixture of corner and edge-sharing CoSe4 tetrahedra. All Co–Se bond lengths are 2.34 Å. Tl1+ is bonded in a body-centered cubic geometry to eight equivalent Se2- atoms. All Tl–Se bond lengths are 3.44 Å. Se2- is bonded in a 4-coordinate geometry to four equivalent Co+1.50+ and four equivalent Tl1+ atoms.
