Syntheses, structures and magnetic properties of four new coordination polymers based on 4′-carboxy-4,2′:6′,4″-terpyridine

Four novel coordination polymers based on 4′-carboxy-4,2′:6′,4′′-tpyridine have been synthesized by changing auxiliary ligand and metal ion under hydrothermal conditions. Compounds 1–4 display 3D network, 2D→3D polycatenated supramolecular and 1D chain structure. Additionally, magnetic properties of complexes 1, 3 and 4 have been investigated.
