Syntheses, crystal structures and luminescent properties of six new d10 transitional metal coordination polymers based on bis(benzimidazole) ligands

Six Cd(II) or Zn(II) compounds have been synthesized. Complexes 1, 3 and 4 feature 1D meso-helical chain. Complexes 2 and 5 exhibit similar 1D infinite helical chains. Interestingly, these 1D chains display different metal ions arrangement. Complex 6 possesses a 2D 44-sql network.
