Reactions of Cobalt(II) and Nickel(II) Complexes Containing Binucleating Macrocyclic and Pyridine Ligands with Carboxylic Acids: Formation of Binuclear Co(II), Ni(II) and Tetranuclear Co(II) and Ni(II) Complexes
MetadataShow full item record
The synthesis of new electron transfer agents was studied. Binuclear and tetranuclear cobalt(II) and nickel(II) complexes were synthesized. Originating from a binucleating macrocyclic and tetra-pyridine ligand reactants. Molecular and electronic structure characterization of products was completed through infrared spectroscopy, electronic absorptions (UV/Vis/NIR) spectroscopy, and X–ray crystallography. The spectroscopic measurement confirmed the formation of : [Co2L(O2CCHPh2)(py)2]BF4, [Co4L2(O2CCHPh2)2]BF4, [Ni2L(O2CCHCPh2)(py)2]BF4, and [Ni4L2(O2CCHPh2)2](BPh4)2.MeCN. The molecular geometries of the binuclear cations exhibit one bent macrocyclic ligand, one bridging diphenylacetate ligand, and two syn-pyridine ligands. The tertranuclear species display a cubic M4O4 array of metal ions and phenolate oxygen atoms, two buckled macrocyclic ligands, two bridging diphenylacetate ligands, and no pyridine ligands. Further investigations of these electron transfer agents will be to understand their reactivity, particularly with atmospheric small molecules.
