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

Two organic – inorganic hybrid layered materials, namely poly[( μ -1,4-diaminobenzene- κ 2N:N ′ )[ μ 3-sulfato(VI)- κ 4O:O ′ :O ′ ′ ,O ′ ′ ′ ]manganese], [Mn(SO4)(C6H8N2)]n, 1, and poly[( μ -1,4-diaminobenzene- κ 2N:N ′ )[ μ 3-sulfato(VI)- κ 4O:O ′ :O ′ ′ ,O ′ ′ ′ ]copper], [Cu(SO4)(C6H8N2)]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.
