Nitrogen Bidentate Synthesis, Structure And Properties Of Body Iron, Manganese, Copper Complexes

In this paper , we synthesize a serial of complexes by hydrothermal synthesis and solothermal synthesis, in which central metal ions are Fe²⁺,Mn2+,Cu2+ respectively and the ligand is phen. Meanwhile we choose proper ligands as bridge ligands. These complexes are:[Fe(phen)(AA)Cl2](1),[Fe(2,2'-bipy)(AA)Cl2](2) and [Fe(μ-Cl)₂(phen)]n(3)[Mn(phen)(acac)₂](4) and {Mn3(phen)₂(CH3COO)6}(5)[(CuCl)₂phen]n(6),{Cu2Cl2(BTC)₂(phen)₂Na4}(7)and {[Cu(en)₂]2[Na(HW7O24)].H2O}n (8)Complex1,complex2 and complex4 are monomers. Complex3 exhibits one dimension zigzag chain-like structure, in which Cl- acts as a bridge ligand. Complex5 is a chiral molecule, which contains three manganese ions. Complex6 shows one dimension ladder chain-like structure, in which Cl- acts as a bridge ligand. Complex7 is a two-core copper complex, in which 1,3,5-benzenetricaboxylic acid acts as a bridge ligand. Complex8 is a polytungstate, in which HW7O245- anion is synthesized difficultly.These complexes are characterized by X-ray, IR spectrum, element analysis, electronic paramagnetic resonance(EPR) and thermogravimetry analysis.
