Our knowledge of the compounds containing carbonyl and nitrosyl (NO) group attached to metallic atoms has been greatly extended in recent years, gely through the work of Hieber and Manchot and their collaborators; but structures which have been suggested, especially for the nitrosyl derivaties, are not in every way satisfactory. In this paper an attempt is made to ablish the structures of these compounds on a firmer basis. The nature of the linkage formed between carbon monoxide and a metallic is now well established. In its complexes the CO groups occupies one Co-ordination place as donor-it provides two electrons to form a single link- is shown, for example, by the ferrous pentacyano-compounds of the general formula M3 [ Fe(CN)5 X] where X may be CO, H2 O, NH3 , pyridine, etc. This formation of a single link is in agreement with the Langmuir formula for carbon onoxide, I. :C ::: O : C- ≡ O+ II. M : C ::: O : M- - C ≡ O+
