The crystal structure described by Sr3GdNa(PO4)3F crystallizes in the trigonal P-3 space group. Na(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. Sr(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(4), three equivalent O(3), and one F(1) atom. Gd(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(4) atoms. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(4) is bonded in a 1-coordinate geometry to two equivalent Sr(1), one Gd(1), and one P(1) atom. In the second O site, O(1) is bonded in a 1-coordinate geometry to one Na(1), one Sr(1), one Gd(1), and one P(1) atom. In the third O site, O(2) is bonded to one Na(1), one Sr(1), one Gd(1), and one P(1) atom to form distorted edge-sharing ONaSrGdP tetrahedra. In the fourth O site, O(3) is bonded in a 1-coordinate geometry to three equivalent Sr(1) and one P(1) atom. F(1) is bonded in a trigonal planar geometry to three equivalent Sr(1) atoms. is represented by the CIF file [CIF]
