The oxidations and reductions of 27 singly arsenic bridged dinuclear metal carbonyl complexes were investigated. There are indications that the complexes as a whole are involved in the redox process. However, the expected one and two electron oxidations with concomitant formation of metal-metal bonds were not observed. Electrochemical electron transfers were irreversible. Chemical oxidation and reduction of a selected example resulted in a series of products originating from the primary fission of one metal-arsenic bond.

A number of polynuclear metal carbonyl complexes can be used as substrates for electron attachment reactions induced by the photoionization of N,N,N',N'-tetramethyl-p-phenylenediamine. Theproducts of such reactions are derived from metal carbonyl radicals produced by cleavage of the metal-metal bonds.

The multiphoton photochemistries of a variety of gas phase transition metal carbonyl complexes are investigated by MPI time-of-flight mass spectrometry, and results indicate that molecular fragment ionization can compete with atomization in these systems. Molecular ions detected include a variety of homonuclear and heteronuclear bare metal clusters, metal-sulfur clusters and metal monocarbonyls. Thus, multiphoton excitation of stable metal carbonyl compounds provides a versatile synthetic route to highly unsaturated neutral and ionic gas phase clusters which offers unique product cluster specificity and does not require the use of high temperature sources. The detection under collision-free conditions of bare metal dimers and trimers following MPI of several dinuclear and trinuclear metal cluster carbonyl compounds, respectively, indicates that dissociative CO loss can compete with metal–metal bond cleavage as a primary excited state reaction upon UV photolysis of these systems.

Abstract EPh2 bridged dicyano octacarbonyl dimetalates {Ph2E[Mn(CO)4CN]2}2- are formed by the reaction of bis(carbonyl-metalates) of tin and lead Ph2E[Mn(CO)5]2 with NaN(SiMe3)2. The new dicyano anions can be transformed with trialkyloxonium tetrafluoroborates [R′3O]BF4 or chlor-trimethylsilane and -germane into the corresponding diisonitrile complexes Ph2E[Mn(CO)4CNR′]2 (R′=Me, Et, SiMe3, GeMe3). In the case of Ph2E [Mn(CO)4CNR′]2 (R′=Me, Et; E=Sn, Pb) the two phenyl groups can be removed with dry hydrogenchloride to give Cl2E[Mn(CO)4CNR′]2.NMR and mass spectra are discussed. The vibrational spectra of the new compounds show cis-coordination of the Sn atoms and the cyano or isonitrile ligands in the carbonylmetalate fragments. This is confirmed by the X-ray structure analysis of Ph2Sn[Mn(CO)4CNMe]2 (space group P21/n).
