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.
