Abstract
Small
changes to the reaction conditions differentiate between
two metal–organic frameworks (MOFs), {[Ce<sub>2</sub>(H<sub>2</sub>O)(bpdc)<sub>3</sub>(dmf)<sub>2</sub>]·2(dmf)}<sub><i>n</i></sub> (<b>1</b>) and {[Ce<sub>4</sub>(H<sub>2</sub>O)<sub>5</sub>(bpdc)<sub>6</sub>(dmf)]·<i>x</i>(dmf)}<sub><i>n</i></sub> (<b>2</b>), that were solvothermally
synthesized from cerium(III) nitrate hexahydrate and 2,2′-bipyridine-5,5′-dicarboxylic
acid (H<sub>2</sub>bpdc) in dimethylformamide (dmf). The two compounds
illustrate how the flexibility of the coordination geometry of Ce<sup>III</sup> translates into MOFs, the formation of which readily adapts
to different solvent environments
