A novel Cd~(II) coordination polymer with helical units and mix-connected network topology constructed form 2-propyl-4,5-imidazoledicarboxylate and N-donor co-ligands

摘要

A novel 2D coordination polymer, formulated as [Cd2(Hpimdc)2(bpp)(H2O)]_n (bpp = 1,3-bis(4-pyri-dyl)propane, H3pimdc = 2-propyl-4,5-imidazoledicarboxylate), has been hydro-thermally synthesized and structurally characterized, which shows unusual multifarious helical structures and (3,4)-connected network with (4.8~2)2(4~2.8~3.10) topology. The photoluminescent property and thermal stability of 1 were also discussed.
