Yield:-

Reaction Conditions:

with nitric acid in water; pH=6 - 10 at 20; for 0.166667 h;

Steps:

Synthesis of bis-diethyldithiocarbamate Zn(II)
To a solution of diethyldithiocarbamate (5 mmol) in 50 mL of deionizated water was stirred by 20 min obtaining a pH3O+ = 10. The pH3O+ was adjusted to 6.0 with HNO3 6 mol L-1. Then zinc(II) nitrate (5 mmol) was added to this solution and the pH3O+ was maintained around 6.0. This control was done using a potentiometer and all the synthesis was carried out under stirring at room temperature. The agitation was kept constant for 10 min until a white solid precipitate. This precipitate was filtered under reduced pressure and washed for three times with deionized water. [Zn(DDTC)2] solid was kept under vacuum in a desiccator with sulfuric acid. Elemental analysis (CHN) and atomic absorption, for C10H20N2S4Zn: Found C, 32.85%; N, 7.67%; H, 5.51% and Zn 18.22%. Calculated: C, 33.18%; N, 7.74%; and H, 5.57% and, Zn 18.07%.
