摘　　要：Two long carbon chain alkyl (aqua) Costa type organocobalt complexes (R=C 6H 13 and C 8H 17 ) have been synthesized for the first time and characterized by elemental analysis, UV Vis and 1H NMR. Their inclusion behavior with β cyclodextrin was studied by 1H NMR methods. It was indicated that in aqueous solution supramolecular adducts have been formed, in which the alkyl groups of the guests were included into the cavity of β CD. Cyclic voltammetry methods was also used to study the electrochemical properties of organocobalt complexes in the absence and presence of β CD.
