One‐Pot Multiple Metal–Organic Framework Formation: Concomitant Generation of Structural Isomers or of Drastically Distinct Materials

Abstract

Abstract The solvothermal reaction of 2,5‐dihydroxyterephthalic acid (H 2 dhtp) and magnesium(II) nitrate in N , N ‐dimethylformamide (DMF) led to the simultaneous formation of two structural isomers, namely, the lvt network Mg(dhtp)(dmf) 2 ( 1 ) and the compound Mg 3 (dhtp) 3 (dmf) 6 · 0.75H 2 O ( 2 ) with the pcu α‐Po primitive cubic topology. The same reaction conditions with manganese(II) nitrate and terephthalic acid (H 2 tp) resulted in the concomitant generation of two drastically different metal–organic frameworks (MOFs), namely, Mn 2 (tp) 2 (dmf) 2 ( 3 ) and [Mn(HCOO) 3 ][NC 2 H 8 ] ( 4 ), in which the formato ligands and N , N ‐dimethylammonium cations arise from DMF degradation.
