KSnSe2 is Hazelwoodite-derived structured and crystallizes in the tetragonal I4cm space group. K(1) is bonded in a 8-coordinate geometry to eight equivalent Se(1) atoms. Sn(1) is bonded to four equivalent Se(1) atoms to form edge-sharing SnSe4 tetrahedra. Se(1) is bonded in a distorted hexagonal planar geometry to four equivalent K(1) and two equivalent Sn(1) atoms.
KSnSe2 is Hazelwoodite-derived structured and crystallizes in the tetragonal I4cm space group. K(1) is bonded in a 8-coordinate geometry to eight equivalent Se(1) atoms. There are four shorter (3.46 Å) and four longer (3.58 Å) K(1)-Se(1) bond lengths. Sn(1) is bonded to four equivalent Se(1) atoms to form edge-sharing SnSe4 tetrahedra. There are two shorter (2.76 Å) and two longer (2.78 Å) Sn(1)-Se(1) bond lengths. Se(1) is bonded in a distorted hexagonal planar geometry to four equivalent K(1) and two equivalent Sn(1) atoms.
