Materials Data on Tl2PdSe2 by Materials Project
PdTl2Se2 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Pd2+ is bonded to two equivalent Tl1+ and four equivalent Se2- atoms to form edge-sharing PdTl2Se4 octahedra. Both Pd–Tl bond lengths are 3.00 Å. All Pd–Se bond lengths are 2.52 Å. Tl1+ is bonded in a 5-coordinate geometry to one Pd2+ and four equivalent Se2- atoms. There are two shorter (3.32 Å) and two longer (3.34 Å) Tl–Se bond lengths. Se2- is bonded in a 6-coordinate geometry to two equivalent Pd2+ and four equivalent Tl1+ atoms.
