| Abstract: | The metal‐organic complexes Co2(terpy)2(btec)·H2O 1 (terpy = 2,2′:6′,2″‐terpyridine, btec = 1,2,4,5‐benzenetetracarboxylate) was synthesized by hydrothermal synthesis method, using 1,2,4,5‐benzenetetracarbonitrile, terpy and CoAc2·4H2O. Single crystal X‐ray diffraction showed that each btec4– ligand links four CoII atoms and each CoII atom links to two btec4– ligands forming a 1D double‐chain structure. Furthermore, the chains pack together through short face–face π–π interactions forming a 3D supramolecular structure. Additionally, the magnetic measurements show antiferromagnetic interactions among metal ions for compound 1 . |
