Analysis of factors governing the formation of single-stranded helical coordination polymers from a macrocyclic metalloligand and Ca2+, Mn2+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+ and Pb2+†
Abstract
The high rigidity, asymmetric exoditopic coordination mode, angular orientations of the coordination tops and good coordination adaptability of the metalloligand, the π⋯π stacking between the adjacent metalloligands in the polymeric chains and the coordination characteristics of the nodes are responsible for the formation of the eight 1D helices.
