Anion-directed assembly of two novel cadmium(II) complexes constructed by 2,2′-(1,4-butanediyl)bis(1H-benzimidazole) ligand

Reaction of cadmium(II) with 2,2′-(1,4-butanediyl)bis(1H-benzimidazole) (abbreviated as H2C4BIm), gives a 1D polymer chain complex with chloride as the counterion and a 2D sheet with 4.82 topology with thiocynate as the counterion. This work demonstrates that different anions used in a reaction may play a major role in the diversity of the products.
