Linear-Chain AlPOs Obtained by the Reaction of Amine Phosphates with Al3+ Ions
Three one-dimensional aluminum phosphates [H3N(CH2)3 NH3] [Al(HPO4)(PO4)], I, [H3NCH2CH2(NH3) CH3][NH4] [Al(PO4)2], II, [H3N(CH2)3NH3] [N2H6O2]0.5 [Al(PO4)2], III, containing linear chains of corner-shared four-membered rings have been synthesized by the reaction between amine phosphates and Al3+ ions. The structures consist of macroanionic [Al(PO4)(HPO4)]2- or [Al(PO4)2]3- chains built up from AlO4 and PO4 tetrahedra, in which all the AlO4 vertices are shared but each PO4 has two terminal P-O linkages. The framework negative charge is balanced by the amine related cations holding phosphate chains together through hydrogen bond interactions. The chain with the composition [Al(PO4)(HPO4)] has been observed for the first time.
