Reduction reactions cluster build

In some other cases, the intermetal electron transfer does not occur even during hour-long irradiations. The initial simultaneous reduction reactions of and M are followed by mixed coalescence and association of atoms and clusters with ions, homolog or not. Besides the dimerization of atoms of the same metal into M2 and M 2, coalescence of both types of atoms occurs twice more frequently. Subsequently, mixed coalescence and reduction reactions progressively build bimetallic alloyed clusters according to the statistics of encounters, therefore to the relative initial ion abundance [53]. 

Then alternate association (37) and reduction reactions (38) progressively build bimetallic alloyed clusters according to the statistics of encounters, therefore to the relative initial ion abundance. ... 

Reduction of Ru3(CO)i2 and Os3(CO)i2 with sodium in ether solvents at various reaction temperatures has been found to provide an effective route to HNCC of ruthenium and osmium 382). Although most of the dianions produced by this method had been isolated previously, the study of these reactions has allowed a better understanding of the build-up processes of these clusters.
