Résumé

Two novel coordination polymers have been synthesized using 1,4-cyclohexanedicarboxylic acid (chdcH2) by the solvent diffusion method. In the presence of different solvents, cis and trans conformations of chdcH2 were completely separated. The reaction in DMF/glycol resulted in a 1D chain framework La(cis-chdc)(DMF)2(NO3) (1) and the reaction in DMSO resulted in the formation of a novel 3D ReO3 topology La2(trans-chdc)3(DMSO)4 (2). Additionally, the solvent molecules (DMF and DMSO) also acted as coordination ligands in the formation of extended structures.
