The material described by K2MnSe2 crystallizes in the orthorhombic Ibam space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Mn(1) and six equivalent Se(1) atoms. Mn(1) is bonded to four equivalent K(1) and four equivalent Se(1) atoms to form distorted face-sharing MnK4Se4 tetrahedra. Se(1) is bonded in a 8-coordinate geometry to six equivalent K(1) and two equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
