Novel Iron(II) and Copper(II) Polymeric Coordination Compounds with N,N′-bipyridine-type Ligands: Synthesis and Characterization

Abstract

Two new 1D coordination polymers based on octahedral Fe(II) and square-pyramidal Cu(II) complexes and N,N'-bipyridine-type ligands were synthesized by slow evaporation method. The compounds with the formula {(bpyH2)•[Fe(bpy)2(H2O)2(SO4)2]•2(H2O)}n and {[Cu(bpp)2(H2O)]•(BF4)2•dmf•0.75(H2O)}n, (where bpy= 4,4'-bipyridine and bpp= 1,3-bis(4-pyridyl)propane, dmf= N,N-dimethylformamide) were characterized by thermal analysis, FT-IR spectroscopy and single crystal X-ray diffraction method.
