Werner, Alfred Nobel prize awarded

Alfred Werner (1866 - 1919) was awarded the Nobel prize for chemistry as a recognition of these studies in 1913. 

Metal complexes have characteristic shapes, depending on the metal ion s coordination number. Two-coordinate complexes, such as [Ag(NH3)2]+, are linear. Four-coordinate complexes are either tetrahedral or square planar for example, [Zn(NH3)4]2+ is tetrahedral, and [Ni(CN)4]2 is square planar. Nearly all six-coordinate complexes are octahedral. The more common coordination geometries are illustrated in Figure 20.12. Coordination geometries were first deduced by the Swiss chemist Alfred Werner, who was awarded the 1913 Nobel Prize in chemistry for his pioneering studies.

Alfred Werner s brilliant researches earned him recognition and honors from learned societies throughout the world. He was awarded the Nobel Prize in 1913. But even then the manifestations of arteriosclerosis were appearing. For two more years, new and exciting papers continued to come from his laboratories. He continued to lecture as usual, even though he became more and more eccentric in his demonstrations. In 1915 on medical advice, he retired from his research and teaching positions. Al-...

Alfred Werner (working at the University of Zurich) was awarded the Nobel Prize for Chemistry in 1913 for his pioneering work that began to unravel the previous mysteries of the compounds formed between block metal ions and species such as H2O, NH3 and halide ions. A famous problem that led to Werner s theory of coordination concerns the fact that C0CI3 forms a series of complexes with NH3 ... 

By the mid-1870s Sophus Jergensen in Denmark had systematized the synthetic methods for preparing the coordination compounds that were known at that time, especially those of cobalt(III). Only in 1893 was the mode of bonding in the complexes established, by Alfred Werner (who was awarded the Nobel Prize in 1913 for this work). Werner concluded that most coordination complexes were essentially octahedral, with six ligands bonded to a central metal ion (more or less, one above, one below, and four in the same plane as the metal ion). He deduced that Pd(II) and Pt(II) complexes were... 

The nature and properties of metal complexes have been the subject of important research for many years and continue to intrigue some of the world s best chemists. One of the early Nobel prizes was awarded to Alfred Werner in 1913 for developing the basic concepts of coordination chemistry. The 1983 Nobel prize in chemistry was awarded to Henry Taube of Stanford University for his pioneering research on the mechanisms of inorganic oxidation-reduction reactions. He related rates of both substitution and redox reactions of metal complexes to the electronic structures of the metals, and made extensive experimental studies to test and support these relationships. His contributions are the basis for several sections in Chapter 6 and his concept of inner- and outer-sphere electron transfer is used by scientists worldwide. 

These properties, and those of many other compounds of a similar kind, were brilliantly rationalized by Alfred Werner in 1893. In this year, at the age of only 26, he proposed what is now referred to as his coordination theory , for which he was awarded a Nobel Prize in 1913. Its principal postulates are as follows ... 

The excellence of German chemistry in general, not just of its organic branch, is objectively attested by its share of Nobel Prizes during the first two decades of the award s existence. Of the seventeen prizes awarded between 1901 and 1921 nine were to German chemists Hermann Emil Fischer (1902), Johann Friedrich Wilhelm von Baeyer (1905), Edward Buchner (1907), Wilhelm Ostwald (1909), Otto Wallach (1910), Alfred Werner (1913), Richard Will-statter (1915), Fritz Haber (1918), and Walther Nemst (1920).
