Li3P is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a trigonal planar geometry to three equivalent P(1) atoms. In the second Li site, Li(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 Li(1) and eight equivalent Li(2) atoms.
Li3P is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a trigonal planar geometry to three equivalent P(1) atoms. All Li(1)-P(1) bond lengths are 2.44 Å. In the second Li site, Li(2) is bonded in a 1-coordinate geometry to four equivalent P(1) atoms. There is one shorter (2.52 Å) and three longer (2.74 Å) Li(2)-P(1) bond lengths. P(1) is bonded in a 11-coordinate geometry to three equivalent Li(1) and eight equivalent Li(2) atoms.
