Abstract

The positive and negative ion fast atom bombardment mass spectra of a series of individual and mixed tetraalkylammonium halopentacarbonylchromate salts have been recorded using mixed dimethylformamide + glycerol matrices. Selected ions have been subjected to collision induced dissociation using linked scanning techniques. Extensive cluster ion formation is observed and the data reveal that, although the chloride ion is most easily displaced from [CrX(CO)5]-, iodide is least easy to displace from this ion. The fragmentation of bimetal anions by preferential loss of two CO ligands from one metal seems to indicate that this process is not accompanied by the formation of a metal-metal bond.
