Na3P is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a trigonal planar geometry to three equivalent P(1) atoms. In the second Na site, Na(2) is bonded in a 1-coordinate geometry to four equivalent P(1) atoms. P(1) is bonded in a 11-coordinate geometry to three equivalent Na(1) and eight equivalent Na(2) atoms.
Na3P is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a trigonal planar geometry to three equivalent P(1) atoms. All Na(1)-P(1) bond lengths are 2.84 Å. In the second Na site, Na(2) is bonded in a 1-coordinate geometry to four equivalent P(1) atoms. There is one shorter (2.89 Å) and three longer (3.21 Å) Na(2)-P(1) bond lengths. P(1) is bonded in a 11-coordinate geometry to three equivalent Na(1) and eight equivalent Na(2) atoms.
