The synthesis and pH-dependent behaviour of Re(CO)3 conjugates with diimine phenolic ligands.
In this report we present a study of a series of Re(CO)3 pyridine-imine complexes with pendant phenol groups. We investigated the effects of the position of the phenol hydroxyl group (para, meta or ortho to the imine) on the steric and electronic characteristics of a series of Re(CO)3X(pyca-C6H4OH) compounds, where X = Cl, Br and pyca = pyridine-2-carbaldehyde imine. These compounds can be gene...
متن کاملfac−Re(I)(tricarbonyl) complexes with anionic bidentate ligands
Investigation of the photophysical and photochemical properties of d transition metals, e.g. Ru(II), Re(I) or Os(II), complexes with heteroaromatic diimine ligands (N∩N) is one of the main topics of modern inorganic physical chemistry. In general, the excited state behaviour of such compounds is governed by the interplay between the metal-to-ligand (MLCT) charge-transfer and intra-ligand excite...
متن کاملUltrafast excited-state dynamics of rhenium(I) photosensitizers [Re(Cl)(CO)3(N,N)] and [Re(imidazole)(CO)3(N,N)]+: diimine effects.
Femto- to picosecond excited-state dynamics of the complexes [Re(L)(CO)(3)(N,N)](n) (N,N = bpy, phen, 4,7-dimethyl-phen (dmp); L = Cl, n = 0; L = imidazole, n = 1+) were investigated using fluorescence up-conversion, transient absorption in the 650-285 nm range (using broad-band UV probe pulses around 300 nm) and picosecond time-resolved IR (TRIR) spectroscopy in the region of CO stretching vib...
متن کاملMetal and Ligand Variations in [MX(diimine)(CO)3] (M=Tc, Re) Complexes: Effects on Photocatalytic CO2 Reduction
Two series of complexes MX(diimine)(CO)(3)] (M = Tc, Re) have been prepared, fully characterised and investigated for their ability to act as photocatalysts for the reduction of CO2 to CO. One series consists of complexes with different aromatic diimine ligands while keeping X = Brconstant. The second series describes complexes with diimine = 2,2-bipyridine and variations in the anionic ligand ...
متن کاملHeterometallic bromo-bridged complexes with a Re(CO)3 fragment
Heterobimetallic complexes in which half-sandwich complexes of ruthenium(), rhodium() and iridium() are connected by three bromo-bridges to Re(CO)3 have been prepared from metathesis reactions of [RuBr(μ-Br)(arene)]2 (arene = C6H6, C6H3Et3-1,3,5 or p-cymene) or [MBr(μ-Br)Cp*]2 (M = Rh or Ir) with [Re(μ-Br)(CO)3(C4H8O)]2. The crystal structures of [(arene)Ru(μ-Br)3Re(CO)3] (arene = C6H6 ...
