Two new iron phosphates have been prepared hydrothermally and characterized by single crystal X-ray diffraction. The structure is composed of isolated anionic chains of the tancoite type, [Fe(HPO 4 ) 2 OH] n , consisting of vertex-sharing Fe-O octahedra. The chains are isotypic with those in the ir

A sodium indium hydrogen phosphate hydrate, Na 2 In 2 [PO 3 (OH)] 4 ' H 2 O, was synthesized under mild hydrothermal conditions, and the crystal structure was characterized by the singlecrystal X-ray di4raction method. The structure is of a new type with the following data:
The hydrothermal syntheses and structures of two new open-framework iron phosphates, I, [C 6 N 2 H 14 ][Fe III 2 F 2 (HPO 4 ) 2 (H 2 PO 4 ) 2 ].2H 2 O, II, and [C 6 N 2 H 14 ] 2 [Fe III 3 (OH)F 3 (PO 4 ) (HPO 4 ) 2 ] 2 . H 2 O, are presented. The structures of both I and II consist of FeO 4 F 2 octa
