| Abstract: | The first four examples of organic‐inorganic hybrid lanthanide‐silver heterometallic frameworks, namely, AgLn(μ5‐C2O4)(SO4)(H2O)2] Ln = Eu ( 1 ) and Sm ( 2 )] and AgLn(μ4‐C2O4)0.5(μ6‐C2O4)0.5(SO4)(H2O)] Ln = Tb ( 3 ) and Dy ( 4 )] based on oxalate and sulfate anions were synthesized by hydrothermal reactions of lanthanide oxide, silver nitrate, oxalic acid and sulfuric acid. All structures contain ladder‐like inorganic lanthanide sulfato chains, which are further connected together through silver atoms by oxalate anions with different coordination behavior (μ5‐C2O4: 1 and 2 , μ6‐C2O4 mixed μ4‐C2O4: 3 and 4 ) to generate two types of 3D networks. The luminescent properties of these compounds were also studied. |
