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

<div><p>Two 1-D homometallic coordination polymers <b>1</b> and <b>2</b> 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 <i>π</i><i>π</i> packing interactions. Magnetic investigation of <b>2</b> indicates the presence of antiferromagnetic interactions in 1-D chains.</p></div
