The GmeLin series "Organometallic Compounds" comprises compounds containing at least one carbon-to-metal bond (except cyano compounds, which are considered inorganic). It includes all information in scientific journals, but patents, conference reports, and disserta- tions generally were not reviewed. The volumes published so far are listed on p. V/' Organometallic compounds are classified according to their nuclearity and the bonding mode of the organic ligands nL. Nuclearity means the number of atoms of the title metal in the formula unit disregarding any additional metals that may be present. The term nL designates a ligand bonded by n carbon atoms to one or different atoms of the title metal. As usual, a-bonded 1 L ligands are designated by R. Inorganic ligands (Le., ligands bonded exclusively by elements other than carbon) are generally designated by 0 or X. 0 means donor ligands such as pyridine or phosphanes; m-electron donors are specified by mO. X is reserved for negatively charged ligands or other one-electron donors such as halogens or SnR; bridging X ligands may donate one 3 2 2 2 (~-H), three (~-Cl, ~-OR), or five (~3-1) electrons.Terms such as lL_ 0, 20-X, or 20_ 0_ 0 may be used for multidentate ligands. Heterometals are often designated by M, and bridging elements, bridging groups, or nonmetallic cluster constituents by E. The symbols 1] and ~ follow the IUPAC nomenclature.

The tulip is undoubtedly one of the favourite flowers of Europeans. Therefore, it deserves its own title in the outstanding Floramour series. This series is aimed at all flower enthusiasts and dedicates a photo book specifically to one variety in a new and refreshing way. In a unique manner, authors Karin Greiner and Simone Braun manage to capture and convey the graceful character and aesthetics of the tulip in Floramour: Tulips.In a magnificent homage, the photo book Floramour: Tulips pays tribute to this beloved flower. In addition to beautiful photographs, this coffee table book offers its readers an engaging all-around view of this powerful ornamental plant with informative texts and detailed drawings.Tulips are commonly considered a symbol of prosperity and luxury. In the 17th century, these floral beauties attained a particularly high status in the Netherlands and sparked a veritable tulip mania throughout Europe. At times, the flower bulbs even took on a currency-like character. Tulip breeding became a respectable endeavour, and it is hardly surprising that this led to an impressive diversity of over 4200 tulip varieties.This informative book succinctly discusses the cultural history of the plant. Tulips symbolise beginnings. They are among the heralds of spring in nature and definitively mark the end of winter with their arrival. Even after being cut, they continue to grow and embody vitality like few other flowers.For all tulip fans and flower lovers, Floramour: Tulips is an inspiring portrait and a fitting gift that not only dazzles with stunning images but also boasts a wonderful visual presentation. For those who already own previous Floramour titles, adding Tulips will stylishly expand their collection.Text in English and German.
