✦ Synopsis

The reactions of tris(2-mercaptoethyiamine)cobalt(III), CoLz, with cadmium(II), copper(U) and zinc(II) has resulted in the isolation of [Gi(cOLJ1] -GlBr4, [Zn(CoLJ2] ZnBr4 and [Cu(CuL,),] Br*2Cu-Br. These complexes have been characterized by chemical analyses, electronic and infrared spectra and conductivity measurements. The metal ions, cd, Zn, CU are believed to be coordinated by one CoLf l&and and a bridging bromide. The reactions of tris(2mercaptoethylamine)cobalt(III) with potential reducing metal ions such as Fey or VOq and oxidizing metal ions such as Cr(H,0)g3, UO;", and Ce" has resulted in the isolation of salts of Co(CoL3)p. Possible mechanisms which will result in the formation of the Co(CoL3)i3 cation are discussed.
