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. [WT5HZ]
Two supermolecular adducts involving p-cyclodextrin(β-CD) and long carbonchain alkyl (aqua) cobaltoximes (R= C6H13 and C8H17 ) have been synthesized for the firsttime and characterized by elementary analysis, UV-Vis and H NMR. We used the cyclicvoltammetry methods to characterize the electrochemical behaviour of the inclusion process.In addition, their formation constant Ka was quantitatively determined by using UV-Vismethods. It has been shown that the longer the carbon chain of the alkyl groups are, themore stable the inclusion complexes are. furthermore, by adding n-C8H17Co (DH)2H2O/β-CDto the aqueous solution, it has been found that the formation constant decreased.
