Tricyanidonitridorhenium(V) complexes with 2,2′-bipyridine (bpy) derivatives in which the 4 and 4′ positions were substituted by X, [ReN(CN)3(X2bpy)]- (X = NMe2, NH2, OMe, Me, Cl, and Br), were newly synthesized and characterized. The structures of the new complexes were determined by single-crystal x-ray anal. UV-visible spectra of the complexes in DMSO showed that the peak maximum wavelengths of Re-to-π* bpy-type-ligand charge transfer were at 474-542 nm. Cyclic voltammograms in Bu4NPF6-DMSO showed 1-electron oxidation and reduction waves corresponding to the Re(VI/V) and X2bpy0/- processes, resp. The new complexes and [ReN(CN)3bpy]- showed photoluminescence in the crystalline phase at 295 and 80 K and in DMSO at 295 K. The origin of the emission in DMSO was attributed to the triplet nature of the Re-to-π* bpy-type-ligand charge-transfer transition. D. functional theory calculations showed that the highest occupied and lowest unoccupied MOs were primarily localized on the dxy orbital of the Re and π* orbitals of the bpy-type ligand, resp. Tricyanidonitridorhenium(V) complexes with 2,2′-bipyridine (bpy) derivatives were newly synthesized and characterized. The new complexes and [ReN(CN)3bpy]- showed photoluminescence. The origin of the emission was attributed to the triplet nature of the Re-to-π* bpy-derivative charge-transfer transition.
