Steps:

1 2.3.1.1. [Bis(dimethylcarbamodithioato-kS,kS′)zinc(II)]
General procedure: Solid ZnCl₂ was added to an aqueous solution of sodium N,N-dimethyldithiocarbamate hydrate or ammonium pyrrolidinedithiocarbamate in molar ratio metal-to-ligand 1:2, under vigorous stirring leading to the immediate precipitation of a white solid.
The precipitate was filtered off, washed with water and n-pentane and dried in vacuum over P₄O₁₀, giving a final yield of 75-80%.Found: C, 23.72; H, 4.04; N, 9.12; S, 41.88. Calc. for C₆H₁₂ZnN₂S₄ (M.W. = 305.78 g/mol): C, 23.57; H, 3.96; N, 9.16; S, 41.94%) FT-IR (KBr or nujol, ν_max/cm^{- 1}): ν(N-CSS) = 1525 br; ν_a,s(SCS) = 974, 565; ν(ZnS) = 381. ¹H NMR: δ_H (DMSO-d₆, ppm): 3.38 (12H, s, CH₃N).
¹³C NMR: δ_C (DMSO-d₆, ppm): 44.64 (CH₃-N); 203.72 (CS). EDS calculated element ratio Zn:S = 0.25.
