The shape formed is an oxy-complex, as it is given in the scheme. The studies showed that the ratio MV~+/ MnO_4~- and CV~+/MnO_4 is 1:1. The infrared spectra show that there is no change in the spectrum of the complex and dye, but there is one additional band in the complexes compiling manganese, which band can be ascribed to the bond Mn-O. Some EPR-spectra have been recorded with the aim to be determined whether in the formation of the complex the oxidizing state of manganese is Mn(VII). 收起
