Anions, solvents and spacer ligands assisted hydrogen-bonding coordination frameworks from tripodal ntb ligands

Structures and Fluorescent Properties of Cadmium(II) Complexes with 1D and 2D Structures Based on Tridentate Benzimidazole Ligands

“…For example, the tripodal tris(2‐benzimidazolylmethyl)amine (ntb) ligand yields complexes with a diversity of coordination numbers and geometries. Su and co‐workers have obtained a series of compounds of helical chains, topological layers and borromean networks through assemblies of ntb 14,15. The investigation concerned with the construction of supramolecules by using tridentate ligands containing benzimidazoles is still limited though these ligands can be used as multifunctional building blocks 16,17…”

“…The choice of suitable ligands is an important factor that greatly affects the structure and stabilisation of the coordination architecture (Zheng et al, 2011). The ligands containing benzimidazole or imidazole groups are often employed to prepare coordination polymers with diverse structure topologies and properties (Pan, et al, 2010;Zhuang, et al, 2009;Chen, et al, 2007). However, incorporation both two functional groups into one ligand are still less explored.…”
