Mn(H_3biim)_2_2Cl_2 and Cd(H_3biim)_2_2Cl_2 have been synthesized from H_2biim, their structures were determined by X-ray crystallography. The two complexes have similar structures and both are neutral compounds. One N atom in H_2biim is protonated, forming a H3biim+ cation. The later is an unidentate ligand, the central metal, Cd or Mn is six coordinated and adopts a distorted octahedral environment.

Most of the triazole fungicides are widely used against rusts, powdery mildews and scabs. But triazole fungicides were harmful to fish and other aquatic organisms. And the Environmental Protection Agency has classified TBZ as a "possible human carcinogen" because it caused significant toxicity and reproductive effects on laboratory mice.

但是三唑类杀菌剂对于鱼类和其他水生生物有害，而且由于戊唑醇对老鼠具有毒性和遗传效应，美国环境保护署(Environemt Protection Agency， EPA)把戊唑醇列为&人类可能致癌物质&。
