When the Fe(CO)4 and M(CO)5 (M=Cr, W) groups are co-ordinated in C3v and C4v fashion, respectively, in transition metal carbonyl cluster species they contain two sets of non-symmetry related carbonyl groups. In the application of the spherical harmonic model (SHM) to the interpretation of the infrared spectra of these compounds it proves necessary first to treat these as for a normal, isolated, M(CO)...
The oxidation reaction of [Fe(CO) 4 ] 2- with [AuBr 2 ] - or Au(SEt 2 )Cl complexes in its early stages parallels the corresponding oxidation with silver(I) derivatives by leading in sequence to [Au{Fe(CO) 4 } 2 ] 3- , [Au 4 {Fe(CO) 4 } 4 ] 4- and the unstable [Au 5 {Fe(CO) 4...
