November 30, 2011, marked the 250th anniversary of the birth of Smithson Tennant in Selby, North Yorkshire, UK, a person credited to the discovery of osmium and iridium in a single paper in the Philosophical Transactions of the Royal Society in 1804. The University of York, UK, marked the anniversary with a public lecture by Dr Annie Hodgson in Selby, followed by two events at the University. The scientific event illustrated new applications of both Os and Ir. Luisa De Cola gave a masterly presentation of the new organic light-emitting diodes (OLED) that she has developed, principally using Ir complexes. Luis Oro reviewed imine hydrogenation and related reactions of iridium dihydride complexes. This lecture linked with Anna Peacock's onstration that analogous half-sandwich Os complexes OsCl(picolinate)are active anticancer agents and can even be more effective than their ruthenium analogues.
