| Abstract |
Three different formate-based metal-organic frameworks, [Zn(HCOO) (2) (Bip)], [H (2) N(CH (3) ) (2) ][Zn(HCOO) (3) ] and [Zn (2) (HCOO) (4) (H (2) O) (4) ], were obtained under solvothermal conditions in DMF. [Zn(HCOO) (2) (Bip)] is based on two ligands (formate and 4,4 -bipyridine), while [H (2) N(CH (3) ) (2) ][Zn(HCOO) (3) ] and [Zn (2) (HCOO) (4) (H (2) O) (4) ] only contain the formate ligand. The structural characterization of these compounds shows specific features for each of these networks. Importantly, the work presented herein proves that the formate is a result of DMF decomposition under the acidic solvothermal conditions used, a very relevant point that should be considered when planning solvothermal synthesis of MOFs with organic acids, such as azelaic acid. Three different formate-based metal-organic frameworks were obtained under solvothermal conditions in DMF. Structural characterization of these compounds shows specific features for each of these networks. The formate is a result of DMF decomposition under the acidic solvothermal conditions used.
