The role of bis-pyridyl-bis-amide (bpba) ligands, which possess various active donor atoms (N and O) and different flexible -(CH_2)_n- skeletons, is significant in the construction of coordination polymers. In this report, preparations of different dimensional networks based on the bpba ligands with or without participation of auxiliary polycarboxylate ligands are described, along with an overview of the entanglement and structural transformation of the bpba-based coordination polymers.
