K6WN4 crystallizes in the tetragonal P4_2/nmc space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted bent 120 degrees geometry to two equivalent N(1) atoms. In the second K site, K(2) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. W(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. N(1) is bonded in a 6-coordinate geometry to one K(1), four equivalent K(2), and one W(1) atom.
K6WN4 crystallizes in the tetragonal P4_2/nmc space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted bent 120 degrees geometry to two equivalent N(1) atoms. Both K(1)-N(1) bond lengths are 2.74 Å. In the second K site, K(2) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. There are two shorter (2.78 Å) and two longer (2.88 Å) K(2)-N(1) bond lengths. W(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. All W(1)-N(1) bond lengths are 1.93 Å. N(1) is bonded in a 6-coordinate geometry to one K(1), four equivalent K(2), and one W(1) atom.
