Metal-ammines formation

Bjerrum, J. Metal Ammine Formation in Aqueous Solution. Copenhagen P. Haase and Son 1941. 

Other reactions leading to NH4 removal from soil solution besides microbial nitrogen assimilation, metal-ammine formation, or adsorption onto mineral surfaces, involve NH3 fixation by incorporating it as NH2 in aromatic rings of humic acids (quinone) followed with aromatic ring condensation. 

The larger the value of the constant is, the more stable the complex (Table 12.11). The metal-ammine formation constants Ksl and Kst are known as stepwise formation constants. Stepwise formation constants1 could be used to estimate overall formation constants. For example,...

In 1948, Jannik Bjerrum became the director of KLA and professor at the University of Copenhagen. His dissertation, from 1937, was entitled Metal Ammine Formation in Aqueous Solutions. Bjerrum was a prominent complex chemist, but he never became comfortable with quantum mechanics. He did not make a secret of this, however.
