| Description
| - Electrochemical reactivity patterns have been established by cyclic voltammetry, EPR and UV/Vis spectroelectrochemistry for the transition [(C6Me6)ClOs]+/[(C6Me6)Os] in mononuclear and dinuclear complexes with the 2,2'-azobispyridine (abpy) and 2,2'-bipyrimidine (bpym) bridging ligands. The isolated electron reservoir intermediate {[(.mu.-abpy)[OsCl(C6Me6)]2}•+ could be analyzed by X band and W band EPR with regard to 189Os hyperfine splitting and g anisotropy as an abpy anion radical species with significant contribution from the metal centers. The function of the .mu.-conjugated acceptor ligand in mediating the interaction between two equivalent electron and atom transfer sites was analyzed through simulation of the cyclic voltammograms.

- Model elektrochemické reaktivity byl odvozen na základě cyklické voltametrie, EPR a UV/VIS spektroelektrochemie přechodu [(C6Me6) ClOs]+/[(C6Me6) Os ] v jednojaderných a dvojjaderných komplexech s můstkovými ligandy 2,2'-azobispyridinem (abpy) a 2,2'-bipyrimidinem (bpym). Izolovaný meziprodukt {[(.mu.-abpy)[OsCl(C6Me6)]2}•+ se schopností elektronového rezervoáru mohl být charakterizován pomocí X-band a W-band EPR, vzhledem k 189Os hyperjemnému štěpení se a g-anisotropii, jakožto typ s abpy anion radikálem, s důležitým příspěvkem od kovových center. Funkce z .mu.-konjugovaného akceptorového ligandu ve zprostředkování vzájemné interakce mezi dvěmi rovnocennými centry elektronového a atomového přenosu byla analyzována simulací cyklického voltamogramu.
