Hydrogen‐Bonded Helices in the Layered Aluminophosphate (C₂H₈N)₂[Al₂(HPO₄)(PO₄)₂]

Abstract

Following the discovery of microporous aluminophosphates AlPO 4 -n (n denotes a specific structure type), [1] there is considerable interest in developing new aluminophosphate compounds with novel framework structures because of their potential application in catalysis, adsorption, and separation. [2][3][4][5] The aluminophosphate family encompasses a rich structural variety enhanced by the employment of organic amines as structure-directing agent under hydrothermal/ solvothermal conditions. The diverse arrangements of AlO n polyhedral units (n = 4-6) and P(O b ) n (O t ) 4Àn tetrahedral units

Towards Rational Synthesis of Microporous Aluminophosphate AlPO4-21 by Hydrothermal Combinatorial Approach

“…Toward the goal of rational synthesis, the methodology of combinatorial chemistry will play a significant role in the discovery of new materials [24][25][26]. Recently, combinatorial approach has been successfully applied to the hydrothermal or solvothermal synthesis of zeolite and related open-framework materials [27][28][29][30][31][32]. Using this approach an extensive study of complex multi-component system is easily achieved.…”

Helical Coordination Polymers Based on Keggin‐type POMs and N‐donor Ligand

“…Coordination polymers (CPs), which are emerging as a class of state‐of‐the‐art materials, based on their tremendous potential applications in gas separation, adsorption, storage, nonlinear optics and heterogeneous, etc., have received great interest in recent years . A current useful synthetic method in this field is the use of inorganic building units to construct or modify CPs . Polyoxometalates (POMs), as a kind of excellent inorganic metal‐oxygen clusters, combining the organic ligands exhibit more structural features .…”

A new open-framework structure of nickel complex pillared aluminophosphate [C6N4H20]2[Ni(Al3P4O16)2]

“…However, this work has been proven to be very difficult due to the complexity of hydrothermal and solvothermal chemistry, and the relevant reports are limited [9][10][11][12][13][14]. Only one successful example is that 1-D AlP 2 Pure single crystals of NiAPO-CJ18 were synthesized by hydrothermal reactions of aluminum triisopropoxide (0.3 g, 1.47 mmol), nickel acetate tetrahydrate (0.274 g, 1.10 mmol), orthophosphoric acid (0.34 g, 2.95 mmol, 85 wt%), triethylenetetraamine (TETA) (0.295 g, 2.01 mmol) and distilled water (8 g, 444 mmol) with the initial pH value of 6-7 at 180°C for 5 days in a Teflon-lined stainless steel 15 mL autoclave. The product containing large single crystals in the form of green plates was filtered, washed with distilled water and dried in the air.…”

“…In the last few years, a range of anionic aluminophosphates including 3-dimensional (3-D) framework, 2-D layer, 1-D chain and 0-D cluster structures have been successfully synthesized [1][2][3][4][5][6][7][8], which display a wide variety of Al/P ratios and fascinating structural architectures. This promotes a considerable interest in incorporating transition metals into lower dimensional aluminophosphates associated with terminal P-OH or P@O groups, forming open-framework metal aluminophosphates with novel structure and catalysis property.…”
