Iron, ruthenium and osmium†
Abstract
The aryl [Li(thf)4][Fe(C6Cl5)4] is notable, as is the nitride [Fe(N)(Me3-cyclam-OAc)]2+, the first FeVI compound apart from the ferrate ion. Interest continues in Fe nitrosyl, oxo- and imide species; there is compelling work on three- and four-coordinate iron. In the case of ruthenium, interest continues in olefin metathesis and complexes of ligands such as bipy, phen and terpy, on account of their photochemical properties.
