Al₁₆P₂₀O₈₀H₄·4C₆H₁₈N₂:  A New Microporous Aluminophosphate Containing Intersecting 12- and 8-Membered Ring Channels

New Gallium Phosphate Frameworks Containing 1,4-Diaminobutane and 1,5-Diaminopentane: [NH3(CH2)xNH3][Ga4(PO4)4(HPO4)] and [NH3(CH2)xNH3][Ga(PO4)(HPO4)] (x=4 and 5)

“…In the former, each 8MR contains one hydrogen bonding interaction of the type O 2 (OH)P ¼ O? (HO)PO 3 (O?O, B2.74 ( A) [25], whilst the orientation of the P ¼ O and P-OH groups of the PO 3 (OH) units in the latter preclude any such crosschannel interactions. As a consequence of these differences, the lattice parameter along the b axis is approximately doubled in (I) (B10.1 ( A) compared to that observed for AlPO-HDA and (V).…”

Anorganische Materialien mit offenen Gerüsten

“…Die Nutzung alkoholhaltiger Lösungsmittel brachte auch weiterhin interessante AlPO 4 -Materialien hervor, wie die vor kurzem erfolgte Herstellung von AlPO-HDA zeigt. [55] Die ersten Gallophosphate, die aus überwiegend nichtwäûrigen Lösungsmitteln hergestellt wurden, waren die beiden GaPO 4 s GaPO 4 -M1 und GaPO 4 -M2, die bei verschiedenem Methylamingehalt in Ethylenglycol erhalten wurden. [56] Die Struktur von GaPO 4 -M2 [57] ist einzigartig und besteht aus Achterringkanälen, in denen sich die Methylammoniumionen befinden.…”

[(C4N2H12)3·H2O][(Al2P3O12)2]: A new anionic open-framework aluminophosphate with helical chains and multi-directional intersecting twelve-ring channels

“…The terminal P_O groups protrude into the channels as observed in the interrupted 3D aluminophosphates of JDF-20 [12] and AlPO-HDA [30]. In these structures, the organic structure-directing agents have strong nonbonding interaction with the terminal oxygen atoms attached to the tetrahedral P atoms and other bridging oxygen atoms.…”
