The compound described by Na6WP4 crystallizes in the hexagonal P6_3mc space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 4-coordinate geometry to one P(2) and three equivalent P(1) atoms. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to one W(1), one P(2), and four equivalent P(1) atoms. W(1) is bonded in a distorted tetrahedral geometry to three equivalent Na(2), one P(2), and three equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 8-coordinate geometry to three equivalent Na(1), four equivalent Na(2), and one W(1) atom. In the second P site, P(2) is bonded in a 7-coordinate geometry to three equivalent Na(1), three equivalent Na(2), and one W(1) atom. is represented by the CIF card [CIF]
