Conclusions
-
1.
As a result of chemical and electrochemical reduction the authors convert linear trinuclear osmium carbonyl halides to triangulo-dodecacarbonyl triosmium.
-
2.
They study the polarographic reduction of linear compounds of osmium of the type X2Os3(CO)12 (X=Cl, Br, I). In contrast with C-X bonds in dihaloalkanes, dissociation of Os-X bonds involves a one-electron stage and leads to the formation of osmium carbonyl radicals which are subsequently converted into metal rings.
-
3.
The ease of reduction of compounds of the type X2Os3(CO)12 depends on the electronegativity of the halogen atoms, and increases in the order X=Cl<Br<I.
