Five new Co(II) coordination polymers have been synthesized by solvothermal reactions based on 3,5-bis(pyridin-4-ylmethoxy)benzoic acid (HL).

The long-铿俥xible ligand (HL) is a good candidate to produce interpenetrating architectures.

The secondary dicarboxylic acid ligands play important roles in the spatial connective fashions and the formation of various dimensional compounds.

The magnetism studies show that both 2 and 5 exhibit antiferromagnetic interactions.
