Preparation and Spectral Investigation of Bis[N(2-methyl-phenyl) 4-Nitro-thiobenzamidato] mercury(II), Bis[N(2-methoxy-phenyl) 4-Nitro-thiobenzamidato]mercury(II), and Bis[N(2-chloro-phenyl) 4-Nitro-thiobenzamidato]mercury(II) Complexes

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.

Notes

^a Isolated yield.

^{a a} s, strong; vs, very strong; m, medium; w, weak. υ, stretching frequency; υ_s, 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 = υ_s(C─S) + υ_as(C─S).
