The synthesis, characterization and crystal structure of a tetranuclear cobalt(III) coordination compound, [Co 4 (L) 4 ](HSO 4 ) 2 (SO 4 )·4.1(CH 3 OH)·H 2 O ( 1 ), with thiocarbohydrazone based ligand is reported. This compound can efficiently catalyze the reduction of oxygen (O 2 ) by a weak electron donor ferrocene, (Fc), at the polarized water/dichloroethane interface which was investigated by voltammetry and biphasic shake‐flask experiments. Compound 1 contains four cobalt cores which are connected together by sulphur atoms. By having four cobalt cores this coordination compound provides a multi‐electron transfer system for oxygen reduction reactions. The results also suggest that compound 1 catalyzes decomposition of H 2 O 2 at the interface.
