Tuning the Cerium-Based Metal-Organic Framework Formation by Template Effect and Precursor Selection.

ABSTRACT: The novel metal-organic framework [(CH₃)₂NH₂]₂[Ce₂(bdc)₄(DMF)₂]·2H₂O (Ce-MOF, H₂bdc-terephthalic acid, DMF-N,N-dimethylformamide) was synthesized by a simple solvothermal method. Ce-MOF has 3D connectivity of bcu type with a dinuclear fragment connected with eight neighbors, while three types of guest species are residing in its pores: water, DMF, and dimethylammonium cations. Dimethylamine was demonstrated to have a decisive templating effect on the formation of Ce-MOF, as its deliberate addition to the solvothermal reaction allows the reproducible synthesis of the new framework. Otherwise, the previously reported MOF Ce₅(bdc)_7.5
