    摘要:
    The preparation and spectroscopic properties of monometallic complexes of rhenium(I)tricarbonylbromide coordinated to 6,7-dihydrodipyrido-[2,3-b:3',2'-j]-1,10-phenanthroline (2-4N), 7,8-dihydro-6H-cyclohepta-[2,1-b:3,4-b]-di-1,8-naphthyridine (3-4N), 2,2'-bi-(3-methyl)-1,8-naphthyridine (Me2O-4N), 2,2'-bi-1,8-naphthyridine (O-4N) and 2,7-di(2'-pyridyl)-1,8-naphthyridine (bpnp) are described. The complexes show a low energy electronic absorption band which is solvent sensitive and has been assigned as a t2g --> pi* rhenium-to-ligand charge-transfer band. The CO stretching frequencies were in accord with facial geometry for the complexes. The NMR properties agreed with the IR results, showing the equivalence of the two naphthyridine fragments in the complexes. Electrochemically all the complexes display two reductions and two oxidations in the potential region from +2.0 to -1.6 V. The reduction potential, E(red), for the Re1/Re0 couple shows a good relationship with the lowest energy absorption band.

Final R and Rw factors were 0.0523 and 0.0497, respectively, for 2260 reflections having I > 3σ(I). The central Cu(II) ion is five-coordinate as a result of its being bound by the two central nitrogens of the heterocyclic ligand, two chlorides

The absorbance shifted to a lower energy as the auxiliary ligand became a better donor (4'-NMe(2)tpy) or as the water was deprotonated. Acetonitrile was found to displace water most easily for the complex of 3c, where the ligand is the least planar. Despite promising features, photooxidation
