The structure described by K2ZnSe2 crystallizes in the orthorhombic Ibam space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Zn(1) and six equivalent Se(1) atoms. Zn(1) is bonded to four equivalent K(1) and four equivalent Se(1) atoms to form distorted face-sharing ZnK4Se4 tetrahedra. Se(1) is bonded in a 8-coordinate geometry to six equivalent K(1) and two equivalent Zn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
