Nonaqueous Synthesis and Characterization of a New 2-Dimensional Layered Aluminophosphate [Al3P4O16]3−· 3[CH3CH2NH3]+

Synthesis and Characterization of a New Layered Aluminophosphate [Al3P4O16][(CH3)2NHCH2CH2NH(CH3)2][H3O]

“…3. This 4 Â 6 Â 8 net has been found in several reported aluminophosphate compounds (21,22,27,30,40,41). The sheet structure is featured by a series of capped sixmembered rings.…”

“…The fourth P-O bond lengths for each P atom are 1.479(4) Å , 1.482(3) Å , 1.476(4) Å , and 1.495(3) Å , respectively, which are the shortest among the PFO distances. These distances suggest that each crystallographically distinct P atom possesses one P=O group (11,13,(21)(22)(23)(24)(25)(26)(27)(28)(29)(30). From Fig.…”

“…In recent years, a variety of organically structure-directed aluminophosphates with anionic chains (one-dimensional) (8)(9)(10)(11)(12)56), layers (two-dimensional) (10,11,, and frameworks (three-dimensional) (38,39,(44)(45)(46)(47)57) have been successfully synthesized. Among the two-dimensional layer compounds, six distinct stoichiometries have been found, i.e., Al 13 (13), the anionic inorganic layers are exclusively constructed from tetrahedral AlO 4 and PO 3 (=O) units alternately linked to form 4 Â 6 (25, 28), 4 Â 6 Â 8 (21,22,27,40,41), and 4 Â 6 Â 12 net (23,29) stacked in an AAAA (22,27,30,40,41), ABAB (21,23), ABCABC (42), or ABCDEFA (43), sequences. These compounds are all structure-directed by the organic amines, which reside in the interlayer region and interact with the inorganic host through H-bonds, van der Waals Forces, and coulombic interactions.…”

Dual Function of Racemic Isopropanolamine as Solvent and as Template for the Synthesis of a New Layered Aluminophosphate: [NH3CH2CH(OH)CH3]3·Al3P4O16

“…The band at 2921 cm\ is also characteristic of a primary amine in its protonated form, whereas the bands at 1650, 1538, and 1384 cm\ are related to isopropanolamine (16). The main bands observed in the range of 478}1182 cm\ are associated with the asymmetric stretching and bending vibrations of PO units (17). The thermogravimetric analysis shows a major weight loss occurring at about 2003C accompanied by a distinct endothermic e!ect.…”

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

“…It is featured by capped 6-membered rings (MRs) connected through bridging O atoms. The capped 6-MR is one of common secondary building units (SBUs) in the reported Al 3 P 4 O 3À 16 layers with 4.6.8-net and 4.6.12-net [17][18][19][20][21][22][23][24][25][26][27]. It is worth noting that this type of 4.6-net sheet was previously designed as a hypothetical 2-D Al 3 P 4 O 3À 16 sheet by our group using a computational method [28].…”
