Cover picture: "half-bonds" in an unusual coordinated S4(2-) rectangle (Chem. Asian J. 2/2009).
This stone lantern is known as the "Koto-ji", or "harp-tuner", as it resembles the tuning bridge of the Japanese koto. The six windows of the lantern are said to symbolize the six essential attributes of a perfect garden, such as the one it overlooks: spaciousness, seclusion, artifice, antiquity, abundant water, and broad views. R. Hoffmann et al. report on two synthesized compounds containing the unusual S4(2-) rectangles bound to either Ir or Rh fragments, illuminated by the two lamp windows. Like the Koto-ji lantern, this paper, which suggests the presence of S-S half-bonds, sheds some light in the garden of beautiful compounds. For more information, see their Full Paper on page 302 ff.
