The crystal structure described by Na3Sr3GaP4 crystallizes in the hexagonal P6_3mc space group. Na(1) is bonded in a 4-coordinate geometry to one P(1) and three equivalent P(2) atoms. Sr(1) is bonded in a 7-coordinate geometry to one Ga(1), two equivalent P(1), and four equivalent P(2) atoms. Ga(1) is bonded in a distorted tetrahedral geometry to three equivalent Sr(1), one P(1), and three equivalent P(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 10-coordinate geometry to three equivalent Na(1), six equivalent Sr(1), and one Ga(1) atom. In the second P site, P(2) is bonded in a 8-coordinate geometry to three equivalent Na(1), four equivalent Sr(1), and one Ga(1) atom. is represented by the CIF file [CIF]
