Metal sulfurdioxide complexes are complex chemistry complexes that contain they dont really contain SO2 sulfurdioxide , SO sub 2 sub , bonded to a transition metal . ref name Greenwood Greenwood&Earnshaw2nd ref Such compounds are common but are mainly of theoretical interest. Historically, the study of these compounds has provided insights into the mechanisms of migratory insertion reactions in organometallic chemistry . Bonding modes Sulfurdioxide forms complexes with many transition metals. For the most stable complex the metal is in oxidation state 0 or 1. ref name Greenwood In most cases SO sub 2 sub binds in monodentate fashion, attaching to the metal through sulfur. Such complexes are further subdivided according to the planarity or pyramidalization at sulfur. The various bonding modes are hapticity sup 1 sup SO sub 2 sub , planar meaning that the MSO sub 2 sub subunit forms a plane .
