Ruthenium salts, ammino-derivatives

Ammino-derivatives of Ruthenium Halides—Derivatives of Ruthenium Salts containing a Nitroso-group—Ammino-derivatives of Rhodium Salts— Ammino-derivatives of Palladium Salts. 

All three metals of this group give rise to ammino-derivatives the compositions of which, however, differ considerably. The ammino-derivatives of ruthenium mostly contain a nitroso-group as well as ammonia the ammino-derivatives of rhodium salts closely resemble the cobalt -ammines and the ammino-derivatives of palladium salts correspond to the ammino-derivatives of platinum salts. 

Ammino-derivatives of ruthenium salts are of two classes, namely, those formed by the addition of ammonia to simple ruthenium salts, and those formed where ruthenium, ammonia, and nitroso-group constitute the basic radicle. The first class is small, the second contains a series of derivatives comparable with the ammino-derivatives of platinum. 

Nitrato-salts of the same type as the chloro- or bromo-salts have also been prepared.1 The salts of the aeido-nitroso-tetrammino-ruthenium type are typical aeido-ammino-derivatives.
