Abstract
A REMARKABLE new series of compounds, formed by the direct union of nitrogen peroxide with certain metals, and of a nature somewhat akin to that of the metallic carbonyls recently discovered and investigated by Mr. Mond and his co-workers, are described by MM. Sabatier and Senderens in the September number of the Bulletin de la Société Chimique. It was observed that when vapour of peroxide of nitrogen in a state of tolerable purity was allowed to stream at the ordinary temperature over metallic copper, cobalt, nickel, or iron, these metals being in the finely divided and pure condition obtained by the recent reduction of their oxides by hydrogen, rapid absorption of the nitrogen peroxide occurred with the formation of definite compounds possessing properties of an exceptionally interesting kind. These compounds are solid nonvolatile substances, unlike the metallic carbonyls in this respect, and are represented by the general formula M2NO2, where M represents either of the four metals mentioned. Their discoverers propose the name metaux nitrés, which perhaps may be conveniently rendered into English as nitro-metals.
