KNa2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. K(1) is bonded in a 16-coordinate geometry to four equivalent K(1), three equivalent Na(2), and nine equivalent Na(1) atoms. There are two inequivalent Na sites. In the first Na site, Na(2) is bonded to six equivalent K(1) and six equivalent Na(1) atoms to form a mixture of edge, corner, and face-sharing NaK6Na6 cuboctahedra. In the second Na site, Na(1) is bonded to six equivalent K(1), two equivalent Na(2), and four equivalent Na(1) atoms to form a mixture of distorted edge, corner, and face-sharing NaK6Na6 cuboctahedra.
KNa2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. K(1) is bonded in a 16-coordinate geometry to four equivalent K(1), three equivalent Na(2), and nine equivalent Na(1) atoms. There are three shorter (4.54 Å) and one longer (4.67 Å) K(1)-K(1) bond length. All K(1)-Na(2) bond lengths are 4.34 Å. There are six shorter (4.37 Å) and three longer (4.42 Å) K(1)-Na(1) bond lengths. There are two inequivalent Na sites. In the first Na site, Na(2) is bonded to six equivalent K(1) and six equivalent Na(1) atoms to form a mixture of edge, corner, and face-sharing NaK6Na6 cuboctahedra. All Na(2)-Na(1) bond lengths are 3.77 Å. In the second Na site, Na(1) is bonded to six equivalent K(1), two equivalent Na(2), and four equivalent Na(1) atoms to form a mixture of distorted edge, corner, and face-sharing NaK6Na6 cuboctahedra. There are two shorter (3.68 Å) and two longer (3.70 Å) Na(1)-Na(1) bond lengths.
