A new one-dimensional（ID） fluoroaluminophosphate chain（C4H15N3）[AlPO4F2]（denoted AIPO-CJ28） was synthesized in the concentrated fluoride synthetic medium with a gel composition of 1.0Al（OPr^1）a：1.0H3PO4： 5.4...A new one-dimensional（ID） fluoroaluminophosphate chain（C4H15N3）[AlPO4F2]（denoted AIPO-CJ28） was synthesized in the concentrated fluoride synthetic medium with a gel composition of 1.0Al（OPr^1）a：1.0H3PO4： 5.4DETA：1.3HF：2.0H2O（DETA=diethylenetriamine）. The reagents were mixed directly without introducing additional water solvent. The 1D chain is constructed by alternating AlO2F2 arid doubly bridging PO4 tetrahedra to form the simplest serrate chain. AIPO-CJ28 can be transformed to another 1D aluminophosphate chain A1PO-CSC upon further crystallization at 230 ℃.展开更多
