Abstract
Voltammetric reduction of monothiocyanate complexes of the iron group metals is accompanied by catalytic evolution of hydrogen in two potential regions. Around -1.3 V vs SCE, hydrogen is evolved at the surface of the electrodeposited metal, around -1.6 V at the surface of mercury. The catalyst is the protonated reduced, zero-valent form of the complex which has limited stability. Minor differences in behaviour of the complexes of the three metals are due to different values of their complexation constant.
