| Abstract: | Bis- and, in particular, tetra-substituted ditertiary phosphine and diphosphazane derivatives of Fe2(CO)9] and Ru2(CO)9], readily synthesised by reaction of the appropriate bidentate ligand with Fe2(CO)9] and Ru3(CO)12], respectively, are very susceptible to electrophilic attack by reagents such as halogens and protons; the solid state structure of one of the products Fe2(μ-Br)(CO)4 {μ-(PhO)2PN(Et)P(OPh)2}2]PF6 has been determined by X-ray crystallography. |
