Formation of coordination compounds of Ag(I) - metronidazole - H<sub>2</sub>O
By the method of oxidative capacity and oxidative function it was established that in system Ag (I) - metronidazole - H<sub>2</sub>O at ionic strength 0.1 mol/l, at temperature 308 К and at concentration Ag (I) С<sub>Ag</sub><sup>+</sup>=1×10<sup>-3</sup> mol/l, metronidazole Сmetr=1×10<sup>-2 </sup>mol/l the following complexes are formed: 1) [AgНL(H<sub>2</sub>O)<sub>3</sub>]<sup>+</sup>; 2) [Ag(НL)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>]<sup>+</sup>; 3)[Ag(НL)<sub>3</sub>H<sub>2</sub>O]<sup>+</sup>; 4) [Ag(НL)<sub>4</sub>]<sup>+</sup>.
