The first one-dimensional manganese polymer containing 4,5-dicarboxyimidazole: solvothermal synthesis, crystal structure and magnetic behavior of [Mn(phen)(Hdcbi)]n (H3dcbi=4,5-dicarboxyimidazole, phen=1,10-phenanthroline)

Solvothermal reaction of Mn(OAc)2 · 4H2O with 4,5-dicarboxyimidazole and phenanthroline resulted in a complex [Mn(phen)(Hdcbi)]n 1 in which Hdcbi as a μ2-bridge links two neighboring manganese(II) ions in chelating mode, forming one-dimensional zigzag chain framework. The fitting of magnetic data (J=−0.11 cm−1, zJ′=−0.06 cm−1, g=2.01) indicates weak antiferromagnetic coupling interactions between the Mn(II) sites.
