Synthesis, Characterization and CMC Determination of some Double-Chain Surfactant-Cobalt(III) Complexes

Abstract

Abstract Some new surfactant-cobalt(III) complex ions of the type, cis-[Co(X)2(C14H29NH2)2]3+ (where X = ethylenediamine or 2,2’ bipyridyl or 1,10-phenanthroline) and cis-α-[Co(trien)(C14H29NH2)2]3+ were synthesized and characterized by IR, NMR, UV-Visible electronic absorption spectra, elemental analysis and metal analysis. The critical micelle concentration (CMC) values of these surfactant-cobalt(III) complexes in aqueous solution were obtained from conductance measurements. Specific conductivity data (at 298, 308 and 318 K) served for the evaluation of temperature-dependent CMC and the thermodynamics of micellization (ΔG0 m, ΔH0 m, ΔS0 m).
