Synthesis, Structure And Nature Of The First Transition Metal Carboxylic Acid Functional Coordination Polymers

Design and construction of multi-dimensional functional metal-organic coordination polymers have attracted chemist's much attention in recent years. This is arisen not only for their various intriguing topological structures, but also for their unexpected properties for potential practical applications in material chemistry, such as heterogeneous catalysis, gas sorption, storage and separations, molecular recognition, nonlinear optics, luminescent and magnetic properties. Selection of appropriate multidentate ligands as spacers to link paramagnetic metal ions or metal clusters as nodes is a powerful way for the building of polyfunctional coordination polymers.In this paper, for design and construction of new functional metal-organic coordination complexes, we choice transition-metal ions or metal clusters as nodes, the ligands with carboxylic group as spacers, and 1,10 - phenanthroline or 2, 2' - bipyridine as terminal ligands. And many new coordination complexes, such as (Δ){[Fe(phen)₃][FeNa(ox)₃]}, (Λ){[Fe(phen)₃] [FeNa(ox)₃]}_n, {Mn^II(isotp)(phen)}_n, {Mn^II₃(tp)_6/2(bpy)₂·(dmf)}_n, {Mn^II(tp)(phen)}_n, {[NH₂Me₂]₂[Zn^II₃(tp)₄]·4H₂O}_n, {Ni^II(tp)(OHCH₃)}_n, {Co^II(tp)(phen)(H₂O)}n have been synthesized and characterized by IR, EA, X-ray diffraction analysis CD, Magnetic analysis and luminescent analysis.
