Adducts of co-ordination compounds. Part III. Nitric acid adducts of some ethylenediamine complexes of cobalt(III)
Abstract
The nitrate salts trans-[Co en2XY](NO3), where (a) X = NO2–, Y = Cl–; (b) X = NO2–, Y = NO3–; (c) X = Y = NO3–, form 1 : 1 adducts with nitric acid. The presence of the hydrogen dinitrate anion, [H(ONO2)2]–, in these adducts is demonstrated.
