A New Manganese(Ii) Coordination Polymer Constructed With 5.5 '-(Benzene)-1,4-Diyl)-Bis(Oxy) Diterphthalic Acid: Synthesis, Structure Analysis And Magnetic Properties

A new 2D manganese(II) coordination polymer, namely [Mn(L)(0.5)(2,2 '-bipy)](n)center dot nH(2)O (1), has been constructed hydrothermally based on manganese acetate and the mixed ligands including the 5.5 '-(benzene)-1,4-diyl)-bis(oxy) diterphthalic acid (H4L) and auxiliary 2,2 '-bipyridine (2,2 '-bipy). The compound was characterized by elemental analyses, was characterized by elemental analysis, infrared spectrum and single-crystal and powder X-ray diffractions, and thermal analyses. Single-crystal X-ray diffraction analyses revealed that compound 1 crystallize in the triclinic system, space group P-1. The adjacent Mn(II) ions are bridged by mu(6)-L4- ligands, producing a 2D layer. Magnetic studies for compound 1 demonstrate an antiferromagnetic coupling between the adjacent Mn(II) centers.
