Synthesis and Characterization of a New Organically Templated Aluminophosphite with a Chainlike Structure
2007
A new aluminophosphite (H4bape)0.5[Al(OH)(HPO3)2] has been synthesized under hydrothermal conditions and its structure was determined by single-crystal X-ray diffraction (bape = N,N′-bis(2-aminopropyl)ethylenediamine). This compound crystallizes in the triclinic system with the space group (No. 2), a = 6.919(2) A, b = 8.704(2) A, c = 9.786(2) A, α = 77.74(3)°, β = 72.43(3)°, γ = 72.52(3)°, V = 531.08(2) A3, Z = 2. The structure consists of distorted octahedral AlO6 and pseudo pyramidal HPO3, which are connected by vertex oxygen atoms to form a chainlike framework with a Al/P ratio of 1/2. The presence of 1D infinite Al-O-Al linkage in the framework is noteworthy. The organic templates are fully protonated and interact with the aluminophosphite chains through extensive hydrogen bonds to form a 3D supramolecular network.
