A zipper-like double chain coordination polymer constructed from a novel pseudo-macrocyclic binuclear Cu(II) complex

► Pseudo-macrocyclic structure is formed by the linkage of an intramolecular H-bond. ► Complex structure is modulated by the ligand rigidity. ► An interesting supramolecular zipper-like double chain structure is formed. ► Strong antiferromagnetic coupling is mediated by a single alkoxo-bridge.
