Synthesis and Characterization of Some Trinuclear Cobalt(ii) Thiocarbo Xylates

Abstract

Some cobalt(II) complexes of thiocarboxylic acids with the general composition Co(SOCR 0 ) 2 and Co(SOCR 0 )(OOCR) [where R ¼ C 13 H 27 , C 15 H 31 or C 17 H 35 and R 0 ¼ CH 3 or C 6 H 5 ] have been synthesized by substitution reactions and characterized by elemental analyses, spectral studies and magnetic moment measurements. The electrical conductance data indicate that (Co(SOCCH 3 ) 2 is a 1:2 electrolyte while the other complexes are non-electrolytes. IR spectra show the presence of bidentate and bridging modes of coordination for carboxylate and thiocarboxylate anions, respectively. Electronic spectral data and magnetic moment values indicate an octahedral environment around cobalt(II). The plausible structure for the trimeric species has been proposed on the basis of the
