This is only the beginning of a process which ultimately results in the formation of solid state hydroxides or oxides. Actually, the solution species present in neutral or alkaline solutions of transition-metal ions are relatively poorly characterized. The formation of numerous hydroxy- and oxy-bridged polynuclear species makes their investigation very difficult. However, it is clear that there is a near-continuous transition from mononuclear solution species, through polynuclear solution species to colloidal and solid state materials. By the way, the first example of a purely inorganic compound to exhibit chirality was the olated species 9.11. 

Polynuclear transition metal cyanides such as the well-known Prussian blue and its analogues with osmium and ruthenium have been intensely studied Prussian blue films on electrodes are formed as microcrystalline materials by the electrochemical reduction of FeFe(CN)g in aqueous solutionThey show two reversible redox reactions, and due to the intense color of the single oxidation states, they appear to be candidates for electrochromic displays Ion exchange properties in the reduced state are limited to certain ions having similar ionic radii. Thus, the reversible...

For di- and polynuclear gold(I) complexes vith two Au(I) centers held in close proximity, a lower energy 5denergy from its mononuclear counterpart is a spectroscopic signature [2, 7, 44]. Excitation to the 5da —> 6pG transition gives rise to a [5da, 6pa] excited state having a formal...

Figure l.4 The structural variety of trinuclear ferric hydroxo complexes, Fe3(OH)f i, that could form from Fe2(OH)24+ at low pH. Iron atoms are indicated as full circles, OH as open circles. The arrow indicates a transition from dinuclears to trinuclears (p = 2 to p = 3), which is realistic as an early step in the growth of polynuclears. (From Crichton, 1991.)... 

Binuclear and polynuclear compounds with direct metal-metal interaction constitute a large class of transition metal complexes which play an important role also in organometallic chemistry. Generally, the frontier orbitals of these compounds are engaged in metal-metal bonding. Consequently, redox processes affect the metal-metal interaction. The same is true for the luminescence of such complexes since it involves also thg frontier orbitals. The binuclear complex Pt2(pop) 36) (pop = diphosphonate) and... 

The excited states which are responsible for the eel of the previous examples are of the CTML type or involved in metal-metal bonding of polynuclear complexes. Photoluminescence, or eel in our case, can also originate from intraligand (IL) excited states provided these states are the lowest excited states of such complexes. IL emissions are characteristic for many transition metal...
