摘要：
The stability and stoichiometry of leading complex in the model system of copper nitrate and tebuconazole (Teb) were evaluated. The successive formation constant for bis-coordinated Cu-Teb species (involved in peak with potential approx. -250 mV) was measured; beta(0) = 7.61 +/- 0.10. The pseudopolarographic measurement indicated the consecutive loss of NO3- group and Cu reduction in more negative accumulation potentials. The structure of an original bis-coordinated species [Cu(II)NO3(Teb)(2)](+) was calculated.
