An organic molecule containing cobalt phosphate (denoted CoPO-GIS) which is isostructural with the zeolite gismondine has been synthesized under solvothermal conditions by using [Co(en)3]Cl3 and phosphoric acid as the reactants and ethylene glycol as the solvent. CoPO-GIS ((H3NCH2CH2NH3)0.5*CoPO4) crystallizes in the monoclinic space group C2/c with a=14.744(3) Å, b=8.850(3) Å, c=10.062(3) Å,β=131.609(19)°, and Z=8. The structure consists of a 3-D network of strictly alternating CoO4 and PO4 tetrahedra interconnected by oxygen bridges, and the charge-balancing diprotonated ethylenediamine cations are highly ordered in the cages of the CoPO4 framework. CoPO-GIS is the only amine-containing cobalt phosphate with a known zeolite topology.

A new layered aluminophosphate [NH3CH2CH(OH)CH3]3' Al3P4O16 containing a racemic mixture of isopropanolamine has been synthesized using isopropanolamine as the predominant solvent and the template and its structure was determined by means of single-crystal X-ray di4raction. The title compound crystallizes in the trigonal space group R31 with M=689.18, a=13.1068(15) A, c=26.935(4) A, Z=6, V=4007.2(9) A3, R=0.0338, and Rw=0.0982. The structure consists of [Al3P4O16]3- macroanionic sheets with a 4

A new layered aluminophosphate [C6H21N4][Al3P4O16] has been synthesized solvothermally by using triethylenetetramine (tetam) as the structure-directing agent and ethylene glycol as the solvent. The structure of the compound was solved by singlecrystal X-ray di4raction analysis. [C6H21N4] [Al3P4O16] crystallizes in the monoclinic space group P21/c with a59.550 (1), b524.064 (1), c59.601(1)As, b597.99 (1)3, V52184.9 (1) As 3 and Z54 (R50.057 and Rw50.052), and its structure consists of [Al3P4O16]3- macroanionic sheets stacked in an AAAA sequence. As primary building units in the individual sheet, alternating PO4 with terminal P5O and AlO4 tetrahedra are corner-shared to form elliptical eight-membered rings as well as four- and six-membered rings. The macroanionic sheets are held together through H bonds between the terminal P5O groups in the inorganic layers and the N atoms of the tetam molecules, which are triply-protonated.

A family of lamellar aluminophosphates designated APO-Ln (L stands for lamellar and n ) 6, 8, 10, 12, the number of carbon atoms for the occluded template molecules) was synthesized from a mixture of phosphoric acid, aluminum triisopropoxide, ethylene glycol and an unbranched primary alcohol in the presence of an amine as the structure-directing template. The compounds were characterized by X-ray powder diffraction, scanning electron microscopy, MAS NMR spectroscopy, differential thermal, and thermogravimetric analyses. The inorganic layers of APO-Ln are composed of PO4, AlO4, and AlO6 structural units, and the ratio of the octahedral Al to the tetrahedral Al in the as-synthesized compounds is about 1:1. APO-Ln exhibit a distinct weight loss when treated at elevated temperatures, and upon dehydration they adsorb a considerable amount of water. Dehydration-rehydration for APOLn materials is reversible with the dehydrated samples containing almost only tetrahedrally coordinated aluminum.

【期刊论文】Mono-sized single-wall carbon nanotubes formed in channels of AlPO4-5 single crystal

An alternative approach to the synthesis of mono-sized and parallel-aligned single-wall carbon nanotubes (WCNs) is reported. The SWCNs are formed in 0.73nm sized channels of microporous aluminophosphate crystallites by pyrolysis of tripropylamine molecules in the channels. They are characterized through transmission electron microscopy, polarized Raman scattering, and electrical transport measurements. Our results would open a door to further detailed studies on the intrinsic properties of carbon nanotubes now in progress.
