Electrospray mass spectra derived from dichloromethane or dichloromethane/methanol solutions of cationic and anionic metal carbonyl compounds are reported for the first time.The cations investigated are the seven coordinate species + (M=Mo, W; P-P = diphosphine or similar ligand; X=F, Cl, Br, I) and carbonyl phosphonium or arsonium cations of the types 1-P-PMe)(η2-P-P)>+ (M=Cr, Mo, W), 1-P-PMe)(η2-P-P)X>+ (M'=Mn, Re).These cations were prepared by the action of MeI on M(CO)3(η1-P-P)(η2-P-P) and M'(CO)2(η1-P-P)(η2-P-P)X, respectively, each of which contains a pendant Group 15 atom.The anionic species investigated are - and -.In all cases the dominant peak in the mass spectrum corresponds to the principal ion known to be present in solution.
