The 1 : 1 cobalt, nickel, copper and zinc complexes of N-methyliminobis(methylenephosphonic) acid, and 1 : 2 cobalt and nickel complexes were prepared. The effect of alkali and alkali earth metals as "external cations" on the crystallization and stoichiometry of solid cobalt complex was investigated. Infrared and electronic spectra and magnetic susceptibilities indicate that cobalt and nickel form high-spin complexes. The coordination sphere of the central atom is formed by a distorted octahedron of the ligand oxygen atoms.

Ionic liquids are critical reagents for science and technical processes nowadays. Metals are the most used reagents in the industry. It is crucial to have a deeper understanding of how ionic liquids and metals could interact. In this article the interaction of those two families of compounds is accessed. The dissolution (reaction) of metals with ionic liquids is studied, namely the influence of temperature, redox potential, and availability of an oxidant in the process. The final state achieved by the iron metal samples was also addressed by Mössbauer spectroscopy.
