Unexpected Co-operation: An open-coordination-sphere cobalt(III) pyridine oxime complex is designed as catalyst for the hydrogen evolution reaction (HER). However, electrochemical alteration in presence of acid leads to the formation of cobalt-based particles that act as efficient HER electrocatalyst at pH 7, pointing to the challenging task of identifying the real catalytic species in the development of new materials.
