Several preparative routes to bis[N(substituted-phenyl) 4-nitro-thiobenzamidato] mercury(II) complexes are presented, including the reaction of mercury(II) oxide, fluoride, chloride, bromide, cyanide, acetate, and nitrate with N(substituted-phenyl) 4-nitro-thiobenzamide derivatives. 1 H-NMR, Raman, and IR measurements confirmed the complexation of mercury to sulphur.

a a s, strong; vs, very strong; m, medium; w, weak. υ, stretching frequency; υs, symmetric stretching; υ as, asymmetric (or antisymmetric) stretching; δ, bending.
b Thioamide-type mode are described as follows: thioamide I = υ (C─N) + δ (CH); thioamide II = υ (C─N) + δ (CH) + υ (C─S), thioamide III = υ (C─N) + υ (C─S), thioamide IV = υs(C─S) + υas(C─S).
