Hydrothermal synthesis of two new fluorinated indium phosphates [InPO4F(Hen)] and [In5P4F3O16(en)3(O H2)2] is carried out in the system In2O3–P2O5–en –HF–H2O (en = ethylenediamine); these have two- and three-dimensional inorganic frameworks respectively, with the latter having ten-membered ring channels spanned by coordinated en; the fluorides bridge exclusively between indium ions and may be linear or bent.
