| 摘 要： | 1 INTRODUCTION Supramolecular chemistry of manganese(II) car- boxylate coordination polymers has been inten- sively studied in recent years, within which ligand design is an important aspect in adjusting the coordi- nation framework and functionalities of the complexes formed[1～4]. Carboxyphenoxyacetic acids (CPOAH2), which have been known to show biological activities and are widely used in agriculture, are a family of multidentate flexible ligands with versatile binding abilities. …

| Abstract: | The coordination polymer of [Mn(m-CPOAH)2(H2O)2]n (m-CPOAH- = 3-carboxyl- phenoxyacetate) has been synthesized and characterized by elemental analyses, IR, TG and single- crystal X-ray diffraction.The title complex crystallizes in the triclinic system, space group P with a = 4.7013(9), b = 5.6822(11), c = 17.758(4) (A), α = 87.39(3), β ＝ 85.39(3), γ = 85.76(3)o, V = 471.18(17) (A)3, Z = 1, Mr = 481.26, Dc = 1.696 g/cm3, μ = 0.770 mm-1, F(000) = 247, R = 0.0385 and wR = 0.1015.The Mn(II) atom assumes a distorted octahedral geometry, involving four carboxyl oxygen atoms from different m-CPOAH- ligands and two coordinated water molecules.The Mn(II) atoms are linked by the m-CPOAH- ligand to form a one-dimensional chain structure along the a axis.The shortest Mn…Mn separation within the polymer is 7.401(4) (A).A three- dimensional supramolecular network is constructed by O-H…O hydrogen bonding interactions. |
