Synthesis and characterization of long chain alkyl costa-type organocobaltcomplexes and their inclusion interaction with beta-CD

Two long carbon chain alkyl (aqua) Costa-type organocobalt complexes (R=C6H 13 and C8H17) have been synthesized for the first time and characterized by elemental analysis, UV-Vis and H-1 NMR. Their inclusion behavior with beta -cyclodextrin was studied by H-1 NMR methods. It was indicated that in aqu eous solution supramolecular adducts have been formed , in which the alkyl groups of the guests were included into the cavity of beta -CD. Cyclic volt ammetry methods was also used to study the electrochemical properties of or ganocobalt complexes in the absence and presence of beta -CD.
