The crystal structure described by K2NSe2 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 8-coordinate geometry to two equivalent N(1) and six equivalent Se(1) atoms. N(1) is bonded in a distorted L-shaped geometry to four equivalent K(1) atoms. Se(1) is bonded in a 7-coordinate geometry to six equivalent K(1) and one Se(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
