Mononuclear and binuclear rhenium(I) carbonyl complexes of 2,4,6-tris(2-pyridyl)-1,3,5-triazine (TPT), [{ReCl(CO)3}n(TPT)] (n=1, 2), and the formation of mixed-metal compounds with Re–TPT–M (M=MnII, CoII, CuII) bonds

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].…”

“…The mixture was stirred for 3 h at room temperature, then the precipitate was filtered off and the bright yellow solid was recrystallized from ethanol. Re(CO) 5 Cl (0.2 g, 0.55 mmol) was added to a degassed solution (30 mL) of 2-nbzen (0.18 g, 0.55 mmol) in CH 2 Cl 2 and toluene (1:2). The mixture was heated at reflux for 2 h, then the solution was concentrated to half volume and n-hexane was added to precipitate the crude material.…”

The reaction of a potentially N2S-donor bis[benzo(thiazole/imidazole)] with the fac-[Re(CO)3]+ and cis-[ReO2]+ cores

“…This pattern is typical for three carbonyls in a fac isomer arrangement [9]. These bands appear at 2024, 1933 and 1891 cm − 1 for 2.…”

Synthesis and characterization of rhenium and technetium-99m tricarbonyl complexes bearing the 4-[3-bromophenyl]quinazoline moiety as a biomarker for EGFR-TK imaging

“…The infrared spectrum of complex 6 shows strong bands in the 2023-1903 cm À1 range, attributed to the symmetric and asymmetric stretch bands of the C^O bond, demonstrating the presence of the tricarbonyl core in the molecule [21,[24][25][26][27].…”
