A complete series of tricarbonylhalidorhenium(I) complexes (abpy)Re(CO)3(Hal), Hal = F, Cl, Br, I; abpy = 2,2'-azobispyridine: Structures, spectroelectrochemistry and EPR of reduced forms
For the 1st time a complete set of tricarbonylhalidorhenium(I) complexes (Hal = F, Cl, Br, I) was studied in a systematical fashion by example of (abpy)Re(CO)3(Hal), abpy = 2,2'-azobispyridine. Crystal structures of chloride, bromide and iodide analogs are now available, showing increasing planarization of the abpy ligand in that order. Cyclic voltammetry, EPR, IR and UV/visible spectroelectrochem. of the reduced formed [(abpy)Re(CO)3(Hal)]·- illustrate that the four halide complexes differ only partially in their properties. The strongest deviations are obsd. for [(abpy)Re(CO)3F]·- which is distinguished by the widest electrochem. potential range but most pronounced chem. lability. In the EPR spectrum the fluoride exhibits the highest isotropic g value (2.0085) and the lowest Re coupling const., which is of the same magnitude (2 mT) as the detectable 19F hyperfine splitting.
