Synthesis and Characterization of a New Organically Templated Aluminophosphite with a Chainlike Structure

A new aluminophosphite (H 4 bape) 0.5 [Al(OH)(HPO 3 ) 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 $P{\bar 1}$ (No. 2), a = 6.919(2) Å, b = 8.704(2) Å, c = 9.786(2) Å, α = 77.74(3)°, β = 72.43(3)°, γ = 72.52(3)°, V = 531.08(2) Å 3 , Z = 2. The structure consists of distorted octahedral AlO 6 and pseudo pyramidal HPO 3 , 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.
