Abstract
A method for manufacturing cobalt complexes having the formula: EQU [Co(NH.sub.3).sub.5 M]T.sub.y wherein M ligands are selected from substituted and unsubstituted C.sub.1 -C.sub.30 carboxylic acids having the formulas: EQU RC(O)O--; said method comprising reacting cobalt (II) complexes having the formula [Co(H.sub.2 O).sub.6 ] T.sub.y (e.g., T is chloride) with concentrated ammonium hydroxide/ammonium chloride, followed by an oxidizing agent (e.g., peroxide), followed by carboxylic acid anhydride of the formula RC(O)O(O)CR.
