K3YN6 crystallizes in the trigonal R32 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to two equivalent N(1) and four equivalent N(2) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to four equivalent N(1) and four equivalent N(2) atoms. Y(1) is bonded in an octahedral geometry to three equivalent N(1) and three equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one Y(1) atom. In the second N site, N(2) is bonded in a 4-coordinate geometry to two equivalent K(1), two equivalent K(2), and one Y(1) atom.
K3YN6 crystallizes in the trigonal R32 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to two equivalent N(1) and four equivalent N(2) atoms. Both K(1)-N(1) bond lengths are 2.99 Å. There are two shorter (2.89 Å) and two longer (2.96 Å) K(1)-N(2) bond lengths. In the second K site, K(2) is bonded in a 8-coordinate geometry to four equivalent N(1) and four equivalent N(2) atoms. There are two shorter (2.89 Å) and two longer (2.95 Å) K(2)-N(1) bond lengths. There are two shorter (3.00 Å) and two longer (3.39 Å) K(2)-N(2) bond lengths. Y(1) is bonded in an octahedral geometry to three equivalent N(1) and three equivalent N(2) atoms. All Y(1)-N(1) bond lengths are 2.28 Å. All Y(1)-N(2) bond lengths are 2.29 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one Y(1) atom. In the second N site, N(2) is bonded in a 4-coordinate geometry to two equivalent K(1), two equivalent K(2), and one Y(1) atom.
