K6ReN4 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 bent 150 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. Re(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 Re(1) atom.
K6ReN4 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 bent 150 degrees geometry to two equivalent N(1) atoms. Both K(1)-N(1) bond lengths are 2.80 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 (2.82 Å) and two longer (3.03 Å) K(2)-N(1) bond lengths. Re(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. All Re(1)-N(1) bond lengths are 1.87 Å. N(1) is bonded in a 6-coordinate geometry to one K(1), four equivalent K(2), and one Re(1) atom.
