The new tribasic N2S2 ligand H3ttfasbz has been synthesized by condensation of 4-thenoyl 2,2,2-trifluoroacetone and S-benzyl dithiocarbazate. On complexation with copper(II) acetate, spontaneous oxidation to the CuIII oxidation state is observed, and the complex [Cu(ttfasbz)] has been isolated and c...
