The crystal structure described by KN2 crystallizes in the orthorhombic Cmc2_1 space group. K(1) is bonded in a 10-coordinate geometry to five equivalent N(1) and five equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to five equivalent K(1) and two equivalent N(2) atoms to form a mixture of corner and edge-sharing NK5N2 pentagonal bipyramids. In the second N site, N(2) is bonded in a 7-coordinate geometry to five equivalent K(1) and two equivalent N(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
