摘要

The present work reports the construction and self-assembly studies of molecular helix and polyhedral coordination cages using a pyridine-pyrazole based asymmetric ligand. Employment of different metals has resulted in different architectures ranging from a one-dimensional helical polymer, [2 × 2] grid to a pentanuclear cage. For all the structures, hydrogen bonding and π-π stacking were found to be instrumental in bringing additional stability to the polymeric networks. Furthermore, chirality and magnetic properties of cobalt and copper complexes have also been investigated.
