3D CoII, NiII, CoII-doped NiII noninterpenetrated ladder-polymers: structural and magnetic studies

Two isomorphous 3D noninterpenetrated Co-II, Ni-II polymers with secondary building units (SBUs) of 1D ladder-shaped chains have been studied through their structures and magnetic properties. To systematically gain insight into the influence of metal ions on the magnetic behaviors, intermediate CoII-doped NiII polymers have been successfully synthesized. All of these complexes display noninterpenetrated 3D ladder structures and possess usual 3,6-connected ant nets. There are also large pores in the structures (49.1%). The magnetic results show that all of them display weak antiferromagnetic interactions. Such a strategy may have advantages for the generation of more interesting and adjustable magnetic materials.
