Preparation and characterization of rhenium(I) compounds with amino ester derivatized diimine ligands. Investigations of luminescence. Crystal structures of Re(CO)3Cl(pyca-β-Ala-OEt) and Re(CO)3Cl(pyca-l-Asp(OMe)-OMe)

Synthesis, spectroscopic studies and crystal structures of ReI(CO)3(NN)Cl complexes with N,N′-bis(substituted benzylidene)ethane-1,2-diamine Schiff base ligands

“…The Re-C bond distances [1.897(4)-1.937(3) Å ] are similar to those in the related complexes [26,27]. Due to the p-donor character induced by the coordinated chloride ligand, the Re-C linkages trans to the Re-Cl linkages are slightly longer than those trans to the Re-N linkages.…”

“…Imino pyridines have been employed recently as multidentate ligands [4], and to prepare polynuclear complexes [5]. There is also interest in the use of iminopyridine ligands having additional functions such as ester [6] or hydroxo [7], capable to anchor them to polymers [8] or biological molecules [9]. On the other hand, more classic complexes of Mn(II), Ni (II) and Fe(II) and other cations with functionalized iminopyridines have been reported to exhibit very interesting properties such as spin crossover [10], second order non-linear optical properties [11], luminescence [12], or mesogenic behavior [13].…”

Tricarbonylrhenium(I) complexes with N,N′-bis(2- and 4-nitrobenzaldehyde)-1,2-diiminoethane Schiff base ligands: synthesis, spectroscopic and crystal structure studies

“…complexes, where L is an a-diimine or other bidentate ligand with N, P or S donor atoms and X is a halide, bridging ligand, nitrogen donor or some other monodentate ligand, due to their potential applications [1][2][3][4][5][6]. These complexes have been employed in the study of electron and/or energy transfer processes [7], chemiluminescent and electroluminescent systems [8][9][10], photoreduction and electroreduction of CO 2 to CO [11,[12][13][14], devices for solar energy conversion [15] and as models for natural photosynthesis [16].…”
