Materials Data on KSnSe2 by Materials Project

Kristin Persson
KSnSe2 is Hazelwoodite-derived structured and crystallizes in the tetragonal I4cm space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. There are four shorter (3.46 Å) and four longer (3.58 Å) K–Se bond lengths. Sn3+ is bonded to four equivalent Se2- atoms to form edge-sharing SnSe4 tetrahedra. There are two shorter (2.76 Å) and two longer (2.78 Å) Sn–Se bond lengths. Se2- is bonded in a 6-coordinate...
