The three‐dimensional lanthanide noninterpenetrating metal–organic frameworks formulated as [Ln(3,5‐pdc)(C 2 O 4 ) 0.5 (H 2 O) 2 ] · H 2 O (Ln = Lu III , Gd III , Tm III and Yb III for complex 1 – 4 , respectively; 3,5‐pdc = 3,5‐pyridinedicarboxylate) were synthesized by hydrothermal reactions of 3,5‐H 2 pdc with lanthanide oxide and perchloric acid. Compound 1 shows (3,4)‐connected (4.8 2 )(4.8 5 ) dmc‐type topological network, and complexes 2 – 4 display the novel (4,5)‐connected (4 4 .6.8)(4 4 .6 2 .8 4 ) xww‐type topology. The lanthanide‐mediated transformation of CO 2 to oxalate under hydrothermal conditions was observed. The fluorescence properties of complexes 1 – 4 were investigated. (© Wiley‐VCH Verlag GmbH & Co.
