The material structure described by K2CdSnSe4 is Hazelwoodite-derived structured and crystallizes in the tetragonal I-42m space group. K(1) is bonded in a 8-coordinate geometry to eight equivalent Se(1) atoms. Cd(1) is bonded to four equivalent Se(1) atoms to form distorted CdSe4 tetrahedra that share edges with two equivalent Sn(1)Se4 tetrahedra. Sn(1) is bonded to four equivalent Se(1) atoms to form SnSe4 tetrahedra that share edges with two equivalent Cd(1)Se4 tetrahedra. Se(1) is bonded in a 6-coordinate geometry to four equivalent K(1), one Cd(1), and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
