A Three-Dimensional Iron(III) Phosphate, [C2N2H10]2[Fe5F4(PO4)(HPO4)6]

A new layered iron fluorophosphate

“…The Fe-O/F-Fe connectivity leads to infinite chains of vertex 6,8,10,21 or edge-sharing 11,12,14 FeF x O 6-x (x = 0-2) octahedra, finite chains e.g. a pentamer 5 , or a trimer which is found in all SBU-6 [18][19][20] and even some unusual clusters 7,13,22,25 . Iron Phosphate framework exclusively built up from isolated iron octahedra surrounded by phosphate groups is very rare 16,17,24,28 .…”

“…The synthetic procedure of the iron phosphate merits some discussion. Encouraged by our earlier investigations 5 we have used Fe(acac) 3 as the source of iron along with different amines. Use of the same molar ratio of the reactants does not lead to the same structure if the iron source is different (e.g.…”

“…Several open-framework transition metal phosphates are known to date 1 , those of iron forming a large family 2 . A series of oxy-fluorinated open-framework iron phosphates are also reported [3][4][5] . Examples of organically templated iron phosphate materials prepared by hydrothermal method, include, one dimensional [6][7][8] , two dimensional [9][10][11][12][13][14][15][16][17] and three dimensional 14,[18][19][20][21][22][23][24][25][26][27][28] units along with the water molecules are intercalated between the iron fluorophosphate layers.…”

A New Three-Dimensional Inorganic−Organic Hybrid Fluorinated−Iron(III) Arsenate: (C6H14N2)[Fe3(HAsO4)2(AsO4)F4]0.5H2O. Hydrothermal Synthesis, Crystal Structure, and Spectroscopic and Magnetic Properties

“…[7][8][9] Among these materials, iron phosphates occupy a first position because they have given rise to a rich structural chemistry. 2,[8][9][10][11][12][13] The open-framework iron phosphates are sometimes synthesized hydrothermally employing fluorine ions, which often get incorporated as a part of the framework and act as a bridge between the iron centers. [10][11][12][13] Since phosphorus and arsenic belong to the same group in the periodic table, arsenates are also interesting anions, in comparison with the phosphates, for use in the attainement of compounds with occluding organic amines.…”

Hydrothermal syntheses and single crystal structural characterization of M(H2O)6(OPTA)2 [M = Co(II), Ni(II), Zn(II); OPTA = 1-oxopyridinium-2-thioacetato]

“…Hydrothermal methods 1 have been employed to obtain new materials, viz. microporous crystals, [2][3][4][5][6] phosphates, [7][8][9][10][11][12] complex oxide ceramics, [13][14][15] and luminescent materials, 16,17 with novel structures and interesting properties. In addition, hydrothermal synthesis finds an important role in guest exchange, 18,19 selective catalytic activity, 20,21 study of origin of life, [22][23][24] and environmental protection.…”
