Synthesis, Structure and Catalytic Properties of Mn(II) Coordination Polymer through in Situ Ligand Reaction

One 2D coordination polymer, namely [Mn(mu(3)-Hdpna)(2,2'-bipy)](n) (1), has been constructed hydrothermally using Hdbna (Hdbna=5-(2,3-dicyanobenzoxy)nicotic acid), 2,2'-bipy (2,2'-bipy=2,2'-bipyridine), and manganese chloride at 160 degrees C. Interestingly, the H(3)dpna (H(3)dpna=5-(2,3-dicarboxylphenoxy) nicotic acid) ligand was generated by in situ hydrolysis of cyano groups in Hdbna. The product was isolated as stable crystalline solid and was characterized by IR spectrum, elemental analysis, thermogravimetric analysis (TGA), and single-crystal X-ray diffraction analysis. Single-crystal X-ray diffraction analysis reveals that compound 1 crystallizes in the triclinic system, space group P (1) over bar. Compound 1 discloses a 2D sheet with an hcb topology. Compound 1 was applied as an efficient heterogeneous catalyst for the cyanosilylation.
