Summary:
As the coordination polymers in the light, Magnetic lifter conductive, magnetic, catalytic and adsorption properties of potential applications has good value

Become the forefront of the most active research areas. Nicotinic acid derivatives in this paper to build components for the ligand, for its assembly into the 27 with

Polymer crystal structure for the analysis, elemental analysis, IR, UV - visible spectroscopy characterization, and their luminescent properties

And magnetic properties were studied.
Selection of 2 - hydroxy acid ligand has been assembled with the rare earth metal ion coordination polymer 14. Among them,

The first four cases have been rare Kagome http://www.999magnet.com/products/131-magnetic-lifter structure coordination polymers. It also received two rare ferromagnetic gadolinium complexes, and

Preliminary study of the strength of ferromagnetic interaction lead to different reasons. Quantitative evaluation of the approximate model using one-dimensional and two-dimensional Pr (Ⅲ), Nd (Ⅲ

) Coordination polymer in the antiferromagnetic interaction between the central ion size.
Of 6 - hydroxy acid ligand to be five one-dimensional structure of rare earth

Coordination polymers. Which Sm (Ⅲ), Eu (Ⅲ), Tb (Ⅲ) and Dy (Ⅲ) complexes showed good luminescence properties. In addition, with gadolinium

Material shows unusual ferromagnetic interaction.
Respectively, 2 - hydroxy acid and 6 - hydroxy acid for the synthesis of two ligands of one-dimensional chain Cu (

Ⅱ) coordination polymer, which display a ferromagnetic and antiferromagnetic interactions, and their magnetic properties for quantitative analysis.


With 2 - [(4'-pyridyl) methylthio-Asian] - nicotinic acid and 2 - [(3'-pyridyl) sub-methylthio] - nicotinic acid for the synthesis of six ligands with different structures

Transition metal coordination polymers, and study of these transition metal coordination polymers of magnetic properties.
