(NH 4 ) 2 PO 3 H, H 2 O crystallizes in the monoclinic system, space group P2 1 /c, with a = 6.322(1) Å, b = 8.323(1) Å, c = 12.676(1) Å, β = 98.84(1) and Z = 4. The structure was refined to R = 0.022 based on 853 independent X‐Rays intensities. Improved dimensions of the tetrahedral PO 3 H 2− ion have been obtained: PH = 1.34(2) and PO = 1.514(2) Å. The geometry of this ion is compared with that of PO 3 F 2− and SO 3 2− ions and we find a decrease of the volume: V F− > V H+ > V lone pair .
