CsPHO3F crystallizes in the triclinic P-1 space group. Cs(1) is bonded in a 5-coordinate geometry to one O(1), three equivalent O(3), and one F(1) atom. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one F(1) atom. H(1) is bonded in a linear geometry to one O(1) and one O(2) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Cs(1), one P(1), and one H(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one P(1) and one H(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one P(1) atom. F(1) is bonded in a single-bond geometry to one Cs(1) and one P(1) atom.
