Two-dimensional Cu^II and first Pb^II coordination polymers based on a flexible 1,4-cyclohexanedicarboxylate ligand displaying different conformations and coordination modes

10.1016/j.ica.2005.07.006

The study focuses on the synthesis and structural characterization of two novel metal-organic hybrid coordination polymers: {Cu(bpo)(chdc)(H2O)0.5}n (1) and [Pb(chdc)(H2O)]n (2). The research utilized several chemicals, including 2,5-bis(4-pyridyl)-1,3,4-oxadiazole (bpo) as a bridging ligand, 1,4-cyclohexanedicarboxylic acid (H2chdc) as a flexible ligand, and metal salts such as Cu(OAc)2·H2O and Pb(NO3)2. The purpose of these chemicals was to create coordination polymers with distinct structural frameworks: complex 1 exhibits a two-dimensional grid-like structure with large porous cavities, while complex 2 represents the first PbII complex with H2chdc, forming a close-knit network. The study highlights the role of these ligands and metal centers in influencing the conformation and coordination modes, contributing to the development of metal-organic frameworks with unique properties.
