T. Takahira et al., DINUCLEAR RHENIUM(III) COMPLEXES WITH A SINGLE OXIDE BRIDGE, [RE-2(MU-O)CL-2(L)(2)](2-BIPYRIDINE OR 1,10-PHENANTHROLINE)() (L=2,2'), Chemistry Letters, (12), 1994, pp. 2315-2318
Two rhenium(III) complexes with a single oxide bridge, [Re-2(mu-O)Cl-2
(L)(2)](2+) (L = 2,2'-bipyridine (bpy) or 1,10-phenanthroline (phen))
were prepared, and the crystal structure of the phen complex was deter
mined. The complexes show four reversible one-electron redox couples,
[Re-2(mu-O)Cl-2(L)(2)](0/+/2+/3+/4+) in acetonitrile. Both Re-2(III,II
I) and Re-2(III,IV) states of these complexes exhibit strong visible a
bsorption bands.
