Böttcher, Hans-Christian (2017): Reaction Behavior of Decacarbonyldimetalates(2-) (M = Cr and Mo) towards the Nitrosyl Carbonyls of Iron and Cobalt. In: Zeitschrift für Anorganische und Allgemeine Chemie, Vol. 643, No. 6: pp. 410-412

The reaction of the nitrosyl carbonyl complexes [Fe(NO)(2)(CO)(2)] and [Co(NO)(CO)(3)] with the decacarbonyldimetalates [M-2(CO)(10)](2-) (M = Cr and Mo) in THF as the solvent at room temperature was investigated. Thereby a substitution of one nitrosyl ligand towards carbon monoxide was observed in each case. Both reactions afforded the known metalate complexes [Fe(NO)(CO)(3)](-) and [Co(CO)(4)](-), respectively. These species were isolated as their corresponding PPN salts [PPN+ = bis(triphenylphosphane)iminium cation] in nearly quantitative yields. The products were unambiguously identified by their IR spectroscopic and elemental analytic data as well as by their characteristic colors and melting points.
