Structural study and properties of a new iron phosphate Rb9Fe7(PO4)10

Low temperature heat capacity Study of Fe(PO3)3 and Fe2P2O7

“…Recently, iron phosphate compounds have attracted considerable research interest in the field of material science due to their outstanding chemical, thermal, electrical and magnetic properties [1][2][3][4][5]. Crystalline and amorphous iron phosphate materials have been developed and applied widely in various technologically important fields such as catalysis [6][7], electrochemistry [8][9][10][11], optical and magnetic materials [12][13][14][15][16], biosensor fabrication [17], bio-absorbable glass fibers [18], industrial coatings [19], and tissue engineering [20]. Moreover, the high chemical durability of iron phosphate glasses makes them suitable as alternative materials for safe immobilization and permanent disposal of a variety of high-level nuclear waste [3,[21][22][23][24][25][26][27].…”

RbZnFe(PO4)2: synthesis and crystal structure

“…Among them, iron phosphates (Redrup & Weller, 2009;Lajmi et al, 2009) are particularly attractive because of their rich crystal chemistry (Moore, 1970;Gleitzer, 1991) and they present interesting and variable physical properties (Elbouaanani et al, 2002;Riou-Cavellec et al, 1999). Among the variety of iron orthophosphates synthesized and characterized over the past three decades, only two rubidium-containing compounds have been reported, namely Rb 9 Fe 7 (PO 4 ) 10 (Hidouri et al, 2010) and RbCu-Fe(PO 4 ) 2 (Badri et al, 2013). In this paper, we report the structure of a new rubidium iron orthophosphate, RbZnFe(PO 4 ) 2 , synthesized during our investigation of the Rb 3 PO 4 -Zn 3 (PO 4 ) 2 -FePO 4 quasi-system.…”

Synthesis and structure of a new family of 3d–4f heterometallic compounds Rb7LnFe6O2(PO4)8 (Ln=Sm, Eu, Gd, Dy): Magnetic properties of the Sm-, Gd-, Dy-derivatives

“…It should be mentioned that an S ¼5/2 spin state is expected for tbp Fe 3 þ in the presence of weak field ligands like O 2 À , although intermediate spin states of S ¼3/2 have been observed in systems with strong field ligands [30][31][32]. Also, it should be mentioned that S¼5/2 spin states have been experimentally determined for similarly related phosphate systems containing Fe(III)O 5 tbp [33,34].…”
