Manganese–molybdenum–diethyldithiocarbamate [MnMoO 2 (Et 2 dtc) 4 (H 2 O)] {Et 2 dtc=diethyldithiocarbamate} complex has exhibited reversible photogalvanic behaviour in aqueous dimethylformamide medium when studied in a Honda cell. The photogalvanic behaviour has been further investigated by varying the pH, temperature and photosensitizers. UV, visible and sunlight were used as the radiation sources. A maximum potential of 345 mV was obtained at 80°C in visible light. The system was found to be reversible for several cycles. A photoelectrochemical cell was constructed by coupling a charged nickel electrode with the complex electrode which incorporates the experimental compound in acetylene black on a nickel substrate. A maximum potential of 1·08 V with 80 μA current was obtained when irradiated with tungsten lamp. Copyright © 1999 John Wiley & Sons, Ltd.
