| Abstract: In the Al(i-PrO)3-H3PO4-en-EG system， two one-dimensional (1D) aluminophosphate chains AlPO-ESC and AlPO-CSC can transform to each other upon addition of some extra amount of en or H3PO4 to the reaction mixture. The transformation process has been studied by XRD and compositional analyses. Introducing Ni2+ cations， the 1D AlPO-CSC chain which acts as BU can be successfully assembled to 3D open-framework NiAlP2O8·C2N2H9(NiAPO-1) by connecting the terminal phosphonyl oxygens with Ni2+ species. |
