本文采用水热法合成了一种具有大孔洞和孔道结构的开骨架磷铝酸盐（记为NKX-6）。以拟薄水铝石和异丙醇铝为铝源，分别制备了截断四面体和八面体形态的NKX-6晶体。用这两个单晶的数据模拟的x射线衍射图表明它们是同一相。单晶分析表明，NKX-6的骨架为[Al7(HPO3)9(OH)6]3，由1,6-己二胺补偿电荷。在空间群P43m （No. 215）中结晶，a = 17.5632(4) a, V = 5417.6(2) A3, Z = 4, μ = 0.513 mm-1, ρcalcd = 1.707 mg/cm3 （CCDC数：617596）。在NKX-6的结构中发现了两种新型的超级alhpo笼（分别命名为超级A型笼和超级B型笼）。超级A型笼由4个龟背状簇和6个冠状簇构成。这让人想起……
In this report, an open-framework aluminophosphite (denoted as NKX-6) with large cavities and channel structure has been synthesized hydrothermally. Two crystals of NKX-6 with truncated tetrahedron- and octahedron-like morphology have been prepared by using pseudo-boehmite and aluminum isopropoxide as the aluminum source, respectively. X-ray diffraction patterns simulated from the data of these two single crystals show they are the same phase. Single-crystal analysis reveals that the framework of NKX-6 is [Al7(HPO3)9(OH)6]3-and charge-compensated by 1,6-hexanediammoniums. It crystallizes in a cubic system, space group P43m (No. 215), with a = 17.5632(4) A, V = 5417.6(2) A3, Z = 4, μ = 0.513 mm-1, and ρcalcd = 1.707 mg/cm3 (CCDC number: 617596). Two novel super-AlHPO-cages (named as super-type A cage and super-type B cage, respectively) have been found in the structure of NKX-6. The super-type A cage is constructed from four turtleback-shaped clusters and six crown-shaped clusters. It is reminiscent of a...
