Conformation change of the cyclohexanedicarboxylate ligand toward 2D and 3D La(III)-organic coordination networks.

2D and 3D structures of La-1,4-cyclohexanedicarboxylates (chdc) coordination networks, have been constructed using flexible chdc ligands which can have cis and trans conformations of two dicarboxylate groups, controlled by the solution pH in hydrothermal reaction conditions.
