Synthesis, crystal structure solution and characterization of two organic–inorganic hybrid layered materials based on metal sulfates and 1,4‐phenylenediamine

摘要

Two organic–inorganic hybrid layered materials, namely poly[(μ‐1,4‐diaminobenzene‐κ 2 N : N ′)[μ 3 ‐sulfato(VI)‐κ 4 O : O ′: O ′′, O ′′′]manganese], [Mn(SO 4 )(C 6 H 8 N 2 )] n , 1 , and poly[(μ‐1,4‐diaminobenzene‐κ 2 N : N ′)[μ 3 ‐sulfato(VI)‐κ 4 O : O ′: O ′′, O ′′′]copper], [Cu(SO 4 )(C 6 H 8 N 2 )] n , 2 , have been synthesized using 1,4‐phenylenediamine (PPD) as an organic template and component (linker). Both materials form three‐dimensional frameworks. The crystal structures were determined using data from powder X‐ray diffraction measurements. The purity and morphology of the compounds were studied by elemental analyses and SEM investigations, and their thermal stabilities were determined by thermogravimetric and nonambient powder X‐ray diffraction measurements, which indicated that 1 is stable up to 537?K and 2 is stable up to 437?K.
