Abstract

The [Co(BH)2(CN)(NO2)]− complex (BH2 = biacetyldioxime) has been obtained by means of an anatation reaction from the [Co(BH)2(NO2)(H2O)] nonelectrolyte with KCN in aqueous solution. The free acid H[Co(BH)2(CN)(NO2)]·4 H2O and 12 derivatives were obtained by double decomposition reactions. The thermal decomposition of some of these compounds was thermogravimetrically studied. Kinetics of the aquotization of the [Co(BH)2(CN)(NO2)]− was investigated in acid solution by following the change of the concentration of the free NO2 −-ions by means of a diazotation reaction. The kinetic parameters of the reaction are given.
