Four quaternary phosphates of antimony, A 3 Sb 3 P 2 O 14 ⋅3H 2 O ( A =Rb, Cs, Tl and NH 4 ) have been prepared by solid state and hydrothermal reactions and structurally characterized by single crystal and powder X‐ray diffraction techniques. They are isostructural with reported K 3 Sb 3 P 2 O 14 ⋅3H 2 O compound and all five of them have layered structure, wherein the hexagonal‐tungsten‐oxide (HTO) related (Sb 3 P 2 O 14 ) 3− anionic layers are interleaved with the A + ions and water of crystallization. K 3 Sb 3 P 2 O 14 ⋅3H 2 O undergoes topotactic ion‐exchange reactions with aqueous solutions of A Cl ( A =Rb, Cs, Tl, NH 4 ) salts, almost quantitatively.
