K2SnN6 crystallizes in the trigonal R-3m space group. K(1) is bonded to twelve equivalent N(1) atoms to form KN12 cuboctahedra that share corners with twelve equivalent K(1)N12 cuboctahedra, faces with six equivalent K(1)N12 cuboctahedra, and faces with four equivalent Sn(1)N6 octahedra. Sn(1) is bonded to six equivalent N(1) atoms to form SnN6 octahedra that share faces with eight equivalent K(1)N12 cuboctahedra. N(1) is bonded to four equivalent K(1) and one Sn(1) atom to form a mixture of distorted edge, corner, and face-sharing NK4Sn square pyramids.
K2SnN6 crystallizes in the trigonal R-3m space group. K(1) is bonded to twelve equivalent N(1) atoms to form KN12 cuboctahedra that share corners with twelve equivalent K(1)N12 cuboctahedra, faces with six equivalent K(1)N12 cuboctahedra, and faces with four equivalent Sn(1)N6 octahedra. There are six shorter (3.16 Å) and six longer (3.24 Å) K(1)-N(1) bond lengths. Sn(1) is bonded to six equivalent N(1) atoms to form SnN6 octahedra that share faces with eight equivalent K(1)N12 cuboctahedra. All Sn(1)-N(1) bond lengths are 2.17 Å. N(1) is bonded to four equivalent K(1) and one Sn(1) atom to form a mixture of distorted edge, corner, and face-sharing NK4Sn square pyramids.
