AbstractTwo new metal-organic frameworks (MOFs), namely [Mn3(atpa) 3(dmf)2] and [Mn2(tpa)2(dmf) 2], were prepared in N,N-dimethylformamide (dmf) from manganese(II) nitrate and two dicarboxylic acid ligands, 2-aminoterephthalic acid (H 2atpa) and terephthalic acid (H2tpa). The molecular structures of these MOFs are compared to two related coordination polymers, namely [Mn3(atpa)2(Hatpa)2] and [Mn 3(tpa)3-(def)2], which were obtained in N,N-diethylformamide (def), to examine the effect of slight ligand or solvent changes on the framework architecture. The four Mn-based MOFs were used as effective Lewis catalysts for the cyanosilylation of acetaldehyde. The four heterogeneous catalytic systems can be re-used without any apparent loss of activity.
