二维磷酸铝是磷酸盐基沸石的重要前体;新的中山大学6号（SYSU-6），|哈达|以N，N，3，5-四甲基金刚烷-1-胺为有机结构导向剂，采用水热法合成了2[Al 2（HPO 4）（PO 4）2]。本文通过单晶/粉末X射线衍射、扫描电子显微镜、能量色散X射线分析、透射电子显微镜、红外和紫外拉曼光谱、固体27 Al、31 P和13 C魔角自旋（MAS）NMR光谱和元素分析对SYSU-6进行了表征。单晶X射线衍射分析表明，SYSU-6属P21/n空间群，晶胞参数a = 8.4119（3），B = 36.9876（12），c = 12.5674（3），α = 90°，β = 108.6770（10）°，γ = 90°，V = 3704.3（2）π 3，Z = 4，R = 5.12%，对8515个观测数据（I > 2σ（I））进行了计算。该结构具有新的4，12-环层骨架拓扑结构，由交替的AlO 4和PO 4四面体连接。有机分子存在于层之间，并与无机骨架氢键结合。这种新型的层为构建具有新型拓扑结构的沸石提供了更大的机会。
Two-dimensional aluminophosphate is an important precursor of phosphate-based zeolites; a new Sun Yat-sen University No. 6 (SYSU-6) with |Hada|2[Al2(HPO4)(PO4)2] has been synthesized in the hydrothermal synthesis with organic structure-directing agent (OSDA) of N,N,3,5-tetramethyladamantan-1-amine. In this paper, SYSU-6 is characterized by single-crystal/powder X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray analysis, transmission electron microscopy, infrared and UV Raman spectroscopy, solid-state 27Al, 31P and 13C magic angle spinning (MAS) NMR spectra, and elemental analysis. The single-crystal X-ray diffraction structure indicates that SYSU-6 crystallized in the space group P21/n, with a = 8.4119(3), b = 36.9876(12), c = 12.5674(3), α = 90°, β = 108.6770(10)°, γ = 90°, V = 3704.3(2) Å3, Z = 4, R = 5.12%, for 8515 observed data (I > 2σ(I)). The structure has a new 4,12-ring layer framework topology linked by alternating AlO4 and PO4 tetrahedra. The organic molecules reside between the layers and are hydrogen-bonded to the inorganic framework. The new type of layer provides a greater opportunity to construct zeolite with novel topology.
