Abstract

A one-dimensional aluminum phosphate, [NH3(CH2)2NH2(CH2)3NH3]3+ urn:x-wiley:00442313:media:ZAAC200390054:tex2gif-stack-2[Al(PO4)2]3—, has been synthesized hydrothermally in the presence of N-(2-Aminoethyl-)1, 3-diaminopropane (AEDAP) and its structure determined by single crystal X-ray diffraction. Crystal data: space group = Pbca (no. 61), a = 16.850(2), b = 8.832(1), c = 17.688(4)Å, V = 2632.4(2)Å3, Z = 8, R1 = 0.0389 [5663 observed reflections with I > 2σ(I)]. The structure consists of anionic urn:x-wiley:00442313:media:ZAAC200390054:tex2gif-stack-3[Al(PO4)2]3— chains built up from AlO4 and PO4 tetrahedra, in which all the AlO4 vertices are shared and each PO4 tetrahedron possesses two terminal P=O linkages. The cations, which balances the negative charge of the chains, are located in between the chains and interact with the oxygen atoms through strong N—H···O hydrogen bonds. Additional characterization of the compound by powder XRD and MAS-NMR has also been performed and described.

Synthese und Struktur des eindimensionalen Aluminiumphosphats [NH3(CH2)2NH2(CH2)3NH3]3+ urn:x-wiley:00442313:media:ZAAC200390054:tex2gif-stack-4[Al(PO4)2]3—

Ein eindimensionales Aluminiumphosphat, [NH3(CH2)2NH2(CH2)3NH3]3+ urn:x-wiley:00442313:media:ZAAC200390054:tex2gif-stack-5[Al(PO4)2]3—, wurde in Anwesenheit von N-(2-Aminoethyl-)1, 3-diaminopropan (AEDAP) hydrothermal dargestellt. Die Kristallstruktur [Pbca, a = 16.850(2), b = 8.832(1), c = 17.688(4)Å, V = 2632.4(2)Å3, Z = 8, R1 = 0.0389, 5663 beobachtete Reflexe mit I > 2σ(I)] wurde mittels Einkristallröntgenstrukturanalyse bestimmt. In der Kristallstruktur sind AlO4- und PO4-Tetraeder über Ecken zu anionischen urn:x-wiley:00442313:media:ZAAC200390054:tex2gif-stack-6[Al(PO4)2]3—-Ketten entlang der b-Achse verknüpft. Die AlO4-Tetraeder sind über sämtliche Ecken verknüpft, die PO4-Tetraeder haben zwei endständige P=O-Bindungen. Die Ketten sind hexagonal gepackt und mit den dazwischenliegenden Kationen über starke N—H···O-Wasserstoffbrücken verbunden. Zusätzlich wurde die Substanz durch Röntgenbeugung an Pulvern und durch MAS-NMR charakterisiert.
