Abstract
Disodium salt of 4,6-dinitro-1-oxobenzo-[6,5-c]-2,1,3-oxadiazolediol-5,7 (I) was synthesized. The experimental dependences of the formation function on the solution pH were obtained by the potentiometric titration method for the reaction of NaOH and HCl with I, and the equilibrium constants for the above reactions were calculated. The reaction of I with HCl gives the acid sodium salt of 4,6-dinitro-1-oxobenzo-[6,5-c]-2,1,3-oxadiazolediol-5,7, which is the coordination compound with the Na+ cation. The title compound was studied by X-ray diffraction.
