“…The occurrence of nitritonitro-bis-(ethylenediamine)-cobalt(III) has also been reported. 12 The formation of these compounds which are unstable and undergo rearrangements in the dry state to form the corresponding stable nitro complexes, indicates that the preparation of all nitro complexes from aquo ions in aqueous solution may involve the formation of intermediate nitrito complexes.…”

cis-Nitritoaquo-, nitroaquo, and dinitritotetramminecobalt(III) nitrates were prepared, and the rates of their conversion to cis-nitroaquo-, irans-nitroaquo-and cis-dinitrotetramminecobalt(III), respectively, were studied. The formation of cisdinitrotetramminecobalt(III) salts from cobalt(II) is discussed.Although irans-dinitrotetramminecobalt (III) salts can be prepared directly from those of cobalt (II),2 salts of the ds-dmitrotetramminecobalt (III) series are only obtained from carbonatotetramminecobalt(III).3'4The purpose of the present paper is to examine more closely the formation of the ds-dinitrotetramminecobalt(III) ion in order to discover why it cannot be made directly from cobalt(II) in large quantities. ResultsThree new complex nitrates in the ds-tetramminecobalt(III)6 *series were prepared. Two of these, ds-nitritoaquo and ds-dinitrito nitrate, were prepared directly from carbonato and dsdiaquo nitrate. Attempts to obtain these dsnitrito complex ions from irans-diaquo nitrate were unsuccessful.
