Ethylenediamine exists predominantly ( 95%) in the gauche-fosm (50), dihedral angle r = 64.0 1.6°. This conformation may be an important factor in the mechanism of complex formation. The C-N length is

The titrimetric determination of soil constituents is most commonly applied to a limited number of soil analyses, namely, organic carbon, nitrogen compounds, carbonates, and chlorides. Determination of acid content by titration is generally not done because the titration curves are not amenable to typical titration analysis. Because of the color of soil and the fact that it is a suspension when stirred, it is often necessary to remove the constituent of interest before titration. In other cases, it is possible to do a direct titration using an appropriate indicator. However, even in these cases, detection of the end point is difficult. 

The unsaturated molecule Y may be carbon monoxide, an olefin, a conjugated diene, an acetylene, a carbonyl compound, various unsaturated carbon-nitrogen compounds, or probably any of several other unsaturated materials. The reactive part of the covalent metal compound is usually a metal-hydrogen, metal-carbon, metal-oxygen, metal-halogen, metal-nitrogen, or metal-metal group. This reaction... 

Metal Hydrides and Metal-Carbon Compounds. Numerous examples of reductions and additions of metal hydrides or alkyls to unsaturated carbon-nitrogen compounds are known. I shall mention only two examples pertinent to this discussion. 

Because of the deficiency in carbon, it was expected that free carbon would not form on carbides made from transition metal halides and any of the above carbon-nitrogen compounds, that are rich in nitrogen. In the reaction ...
