Nitrogen oxide clusters reaction with

The achievable ablation rates depend on the sample composition, the discharge gas and its pressure. As a filler gas a noble gas is normally used. Indeed, in the case of nitrogen or oxygen, chemical reactions at the sample surface would occur and disturb the sputtering, as electrically non-conductive oxide or nitride layers would be formed. Furthermore, reactions with the ablated material would produce molecular species, which emit molecular band spectra in optical atomic spectrometry or produce cluster ion signals in mass spectrometry. In both cases severe spectral in-... 

Under various conditions Fe8(CO)i2 reacts with a wide range of nitrogen and oxygen bases to form tetra-, tri-, di-, or mononuclear carbonyl anions (153). The tetranuclear cluster is formed in the reaction of Fe3(CO)i2 with pyridine (195), pyridine iV -oxide and dimethyl sulfoxide (187) Fe3(CO)ff results from reaction with ethylenediamine... 

Subsequent reports by Whitmire (30b) have shown that a further anionic cluster, viz. [Tl2Fe6(CO)24]2 (20) (see Fig. 9), is formed by oxidation of 17 and that reactions of 17 with a variety of bidentate nitrogeneous bases afford the anionic monothallium complexes 21a-d (31).
