K Na Na P
KNa2P crystallizes in the triclinic P1 space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Na(1), three equivalent Na(2), and three equivalent P(1) atoms. There is one shorter (2.69 Å) and one longer (3.11 Å) K(1)-Na(1) bond length. There are a spread of K(1)-Na(2) bond distances ranging from 2.96-3.93 Å. There are a spread of K(1)-P(1) bond distances ranging from 3.40-3.87 Å. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one P(1) atom. The Na(1)-P(1) bond length is 3.03 Å. In the second Na site, Na(2) is bonded in a 2-coordinate geometry to three equivalent K(1) and two equivalent P(1) atoms. There is one shorter (2.38 Å) and one longer (2.84 Å) Na(2)-P(1) bond length. P(1) is bonded in a 3-coordinate geometry to three equivalent K(1), one Na(1), and two equivalent Na(2) atoms.
