Structures and spectroelectrochemistry (UV–vis, IR, EPR) of complexes [(OC)3ClRe]n(abpy), n=1, 2; abpy=2,2′-azobispyridine

Tautomerization of 2-nitroso-N-arylanilines by coordination as N,N′-chelate ligands to rhenium(i) complexes and the anticancer activity of newly synthesized oximine rhenium(i) complexes against human melanoma and leukemia cells in vitro☆

“…Bond lengths Re-CO are in the expected range for fac-Re(CO) 3 X-complexes with quinoid ligands [46,65], just as well as the Re-X (X=Cl, Br) bonds. The Re-CO ax bond in trans-position to the halogenido ligand is considerably shorter than the Re-CO eq bonds.…”

Ligand Variations in [ReX(diimine)(CO)3] Complexes: Effects on Photocatalytic CO2 Reduction

“…Complex 15 shows a very high reduction potential of E 1/2,red = +50 mV as the additional electron is localised in its unusual LUMO at the azo-bridge. [29] The electrochemistry of 14, its molecular structure shown in Figure 6, is special since the phd ligand is formally an ortho-benzoquinone system. The first reduction already occurs at -15 mV and generates a strongly stabilised semiquinone radical.…”

Synthesis, crystal structure and spectrothermal characterization of zinc(II) salicylato complex with 2,2′-azobispyridine, [Zn(Hsal)2(H2O)(abpy)]·H2O

“…The Scheme 1. [20], (abpy)Re (CO) 3 Cl [5], [(abpy)Ru](PF 6 ) 2 [21] come close to situation IIb with the pyridyl-N directed toward the chelate metal atom. But in this paper, it can be seen that the abpy ligand adopts an s-cis/E/s-cis conformation, although it adopts in above references s-cis/E/s-trans conformation.…”
