Syntheses, crystal structures and magnetic behaviors of three MnII-terephthalate coordination polymers containing terminal ligands

Three coordination polymers have been synthesized and the structure analyses show that they are all composed of Mn atoms as nodes and terephthalate dianions as spacers. Interestingly, compound 1 consists of 1D infinite zigzag chains, while compound 2 consists of 2D sheets and compound 3 has a 3D framework structure. The study of the temperature dependent magnetic susceptibilities revealed that all of the polymers show antiferromagnetism.
