Complexes of Group 12 Metals with 2-Acetylpyridine 4 N-Dimethylthiosemicarbazone and with 2-Acetylpyridine-N-oxide 4 N-Dimethylthiosemicarbazone: Synthesis, Structure and Antifungal Activity
Reaction in ethanol of group 12 metal halides with 2-acetylpyridine 4 N-dimethylthiosemicarbazone (H4DML) and with 2-acetylpyridine-N-oxide 4 N-dimethylthiosemicarbazone (H4DMLO) afforded complexes of the forms [M(H4DML)X 2 ] (1 - 9) and [M(H4DMLO)X 2 ] (10 - 18) (M = Zn II , Cd II or Hg II X = Cl,...
