Synthesis, structure, and characterization of two 1-D homometallic coordination polymers based on carboxylate-functionlized salen ligands

Two 1-D homometallic coordination polymers 1 and 2 have been prepared by one-step hydrothermal reactions of carboxylate-functionalized salen ligands with Co(II) and Mn(II), respectively. Single-crystal X-ray diffraction analyses reveal that both the 1-D chains give 3-D supramolecular structures through intermolecular hydrogen bonds and ππ packing interactions. Magnetic investigation of 2 indicates the presence of antiferromagnetic interactions in 1-D chains.
