Ion exchange reactions of n-butylamine intercalates of tin(IV) hydrogen phosphate and hydrogen uranyl phosphate with cobalt(III) complexes

Abstract

The ion exchange reactions of n-butylamine intercalates of tin(IV) hydrogen phosphate and hydrogen uranyl phosphate towards carbonatotetraamminecobalt(III), chloropentaamminecobalt(III), and hexaamminecobalt(III) have been investigated. Independent of the complex cation charges, the amounts of Co(III) complex exchanged by the n-butylamine intercalate of tin(IV) hydrogen phosphate are practically the same. With the n-butylamine intercalate of hydrogen uranyl phosphate, the ionic exchange was completed and the composition was fixed by the exchanged Co(III) complex. The layer charge densities of these phosphates justify the different ionic exchange behaviour observed towards the large complex cations. All the products were characterized by chemical analysis, X-ray diffractometry, infrared spectroscopy, diffuse reflectance spectroscopy, and thermal analysis.

“…In addition, certain uranyl compounds such as hydrogen uranyl phosphate (HUP) [40][41][42][43] and Cs 4 [(UO 2 ) 2 (V 2 O 7 )O 2 ] [44] have been shown to exhibit high cationic conductivities. In order to evaluate the potential for ion-exchange reactions of alkali metal cations with 1, samples were equilibrated with 0.01 M solutions of NaCl/NaOH, KCl/KOH, or CsCl/CsOH.…”

“…Based on these new structures, the topological relations can be discerned [5] and used as a basis for materials design yielding solids with specific properties: e.g. selective ion-exchange [6][7][8][9][10][11][12], mixed-valency [13,14], ionic conductivity [15][16][17][18][19][20], enhanced fluorescence [21][22][23], magnetic ordering [11,24], non-linear optical properties [12,25], and differential gas absorption [26,27].…”

“…Clearfield and co-workers have demonstrated that in the synthesis of uranyl phosphonates, the presence of sterically demanding organic groups on the phosphonate ligands leads to the formation of novel structure types, including porous structures. − Second, these materials may be envisioned to exhibit useful catalytic, ion-exchange, and intercalation properties. For example, hydrogen uranyl phosphate (HUP) is a fast hydrogen ion conductor and a versatile ion-exchange reagent, − and Hutchings et al recently demonstrated that uranium oxide-based materials are effective oxidation catalysts for the destruction of a range of hydrocarbon- and chlorine-containing industrial pollutants . Finally, the existence of a number of stable oxidation states of actinides, such as uranium, offers the possibility of synthesising materials with useful optical and magnetic properties.…”
