Synthesis
The ion was originally isolated as the hydrated salt (2(C4H4N2)(O3SC6H4CH3)5.3H2O). It is prepared in two steps from the monoruthenium pyrazine complex:
- 2+ + 2+ → 2(C4H4N2)]4+ + H2O
- 2(C4H4N2)]4+ + Ag+ → 2(C4H4N2)]5+ + Ag
The Creutz-Taube ion illustrates the advantages of ruthenium complexes for examining redox reactions. Ru(II) and Ru(III) ions can be interconverted at mild redox potentials or using conventional redox reagents. Importantly, coordination complexes of both of these oxidation states are kinetically inert, because they are both low-spin, d6 and d5, respectively. Many analogues of this ion have been prepared using different bridging ligands.

Famous quotes containing the word synthesis:
“It is not easy to construct by mere scientific synthesis a foolproof system which will lead our children in a desired direction and avoid an undesirable one. Obviously, good can come only from a continuing interplay between that which we, as students, are gradually learning and that which we believe in, as people.”
—Erik H. Erikson (20th century)
“The new shopping malls make possible the synthesis of all consumer activities, not least of which are shopping, flirting with objects, idle wandering, and all the permutations of these.”
—Jean Baudrillard (b. 1929)
“The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
—Henry Brooks Adams (1838–1918)
