Zusammenfassung
Both the Creutz-Taube ion [(H3N)5Ru(m-pz)Ru(NH3)5]5+ (I) and the new stable complex [mer-(OC)3(PR3)2W(m-pz)W(PR3)2(CO)3]+ (II; R = CHMe2) contain d5/d6 mixed valent metal centers bridged by pyrazine (pz). II is distinguished from I by stronger charge-transfer interaction, higher comproportionation const., lower intervalence transition band energy and less pronounced g anisotropy in the ESR spectrum. Vibrational data suggest delocalized structures for both systems. [on SciFinder(R)]
