Solvent controlled assembly of four Mn(ii)-2,5-thiophenedicarboxylate frameworks with rod-packing architectures and magnetic properties

To investigate the role of solvents on the self-assembly of coordination frameworks, the reactions between MnCl sub(2).4H sub(2)O and thiophenedicarboxylate (thb) ligand in different solvents at 120 degree C produced four new Mn-thb complexes. These Mn-thb frameworks all use a rod-and-spacer assembl...

Summary:To investigate the role of solvents on the self-assembly of coordination frameworks, the reactions between MnCl sub(2).4H sub(2)O and thiophenedicarboxylate (thb) ligand in different solvents at 120 degree C produced four new Mn-thb complexes. These Mn-thb frameworks all use a rod-and-spacer assembly mode, but their rod-packing architectures are totally different because of the structure-directing effect of solvents. The topologies of 1, 2, 3 and 4 are novel (3,5)-connected net, hex, irl and sra, respectively. The results reveal that solvents with different conformations play a significant role in promoting the diversity of structures. In addition, the magnetic properties of 1, 2 and 3 have also been studied.
