| Abstract: | The reaction of the nitrosyl carbonyl complexes Fe(NO)2(CO)2] and Co(NO)(CO)3] with the decacarbonyldimetalates M2(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. |
