In 50 ml of water, 13 g (0.02 mole) of an aqueous 48% sodium N-(2-mercaptoethyl)-ethylenebisdithiocarbamate was stirred at 45° to 50° C. The remaining part of the procedure was performed under a current of nitrogen gas. To the resultant sodium salt solution, 9.5 g (0.02 mole) of an aqueous 26.5% manganous chloride solution was gradually added dropwise at temperatures of 40° to 50° C. After the dropwise introduction, the resultant mixture was stirred at 45° C. for one hour. The crystals which consequently educed in the solution were separated by filtration and washed with water. The washed crystals were dried under a vacuum to produce manganese N-(2-mercaptoethyl)-ethylenebisdithiocarbamate (61). The compounds produced by this procedure were as follows:
