Six Ru26+ derivatives of the form Ru2(L)4(C
CC6H5)2, where L = 2-Fap, 2,3-F2ap, 2,4-F2ap, 2,5-F2ap, 3,4-F2ap, or2,4,6-F3ap, are synthesized and characterized as to their electrochemical, spectroscopic, and/or structural properties.These compounds are synthesized from a reaction between LiCCC6H5 and Ru2(L)4Cl. Two of the investigatedcomplexes exist in a (4,0) isomeric form while four adopt a (3,1) geometric conformation. These two series ofgeometric isomers are compared with previously characterized (4,0) Ru2(ap)4(CCC6H5)2, (4,0) Ru2(F5ap)4(CCC6H5)2, and (3,1) Ru2(F5ap)4(CCC6H5)2. The overall data on the nine compounds thus provide an opportunityto systematically examine how the electrochemical and structural properties of these Ru26+ complexes vary withrespect to isomer type and electronic properties of the bridging ligands.
