“…In the 13 C NMR spectrum of (20), the carbon resonances for the three carbonyl ligands appeared at 197.2 and 190.0 ppm with the intensity ratio of (2:1), which were assigned to carbonyl ligands trans to nitrogen and chlorine, respectively. These values and assignments are in good agreement with the values reported in the literature (Canadas et al, 2019). The IR spectrum showed three strong IR bands at 2017, 1912 and 1878 cm -1 for carbonyl ligands.…”

“…This work was further extended to investigate the coordination modes of bulky P,N donor ligands Z-3-diphenylphosphino-( 1R)-(+)camphor dimethylhydrazone L 7 and diphosphine have been used to prepare many different rhenium complexes including 2D and 3D metallacycles (Gupta & Sathiyendiran, 2018;Canadas et al, 2019;Blanco-Rodr´ıguez et al, 2009;Coogan et al, 2009). [ReX(CO) 5 ] (X = Cl, Br) has been used to polymerize 4-vinyl-1-cyclohexene diepoxide photochemically and thermally without cocatalysts (Abu-Abdoun, 2019).…”

“…Rhenium(I) carbonyl complexes of the type fac-[ReX(N^N)(CO) 3 ] (1) (Figure 3) containing bidentate nitrogen donors are easy to prepare (Canadas et al, 2019;Deeba et al, 2021). These complexes are quite stable at room temperature, and photophysical properties can be tuned by using different types of ligands and by varying the R group.…”

Reaction of 1,10-phenanthroline-5,6-dione V with 1,3-diphenyl propan-2-one afforded the keto-alcohol VI. Treatment of VI with alkynes, di(3-thienyl) acetylene and di(4-tert-butylphenyl) acetylene yielded 5,8-diphenyl-6,7-di(3-thienyl)-1,12-diaza-triphenylene L 1 and 6,7-di(4-tert-butylphenyl)-5,8-diphenyl-1,12-diazatriphenylene L 2 , respectively. [ReCl(CO) 5 ] reacted with N^N-donor ligands L 1 -L 6 to produce fac-tricarbonylrhenium(I) complexes ( 20)-( 25) in good yields as coloured solids. Treatment of [ReCl(CO) 5 ] with the bulky P^N ligand L 7 formed the neutral complex fac-[ReCl(CO) 3 (L 7 )] ( 26) whilst with the azine diphosphine Z,Z-L 8 afforded the cationic complex fac-[Re(CO) 3 (E,Z-L 8 )]Cl (27a), where L 8 is a tridentate ligand. The chloride anion of the complex (27a) was replaced by treating it with NH4PF6 into fac-[Re(CO) 3 (E,Z-L 8 )]PF 6 (27b). Above complexes were characterized by a combination of elemental analysis, IR, Mass and NMR spectroscopy.

“…With reference to the same functional groups, the reactivity of rhenium dicarbonyl complexes was markedly different from that of closely related tricarbonyl species. The latter fac-[Re(CO) 3 ] + core reacted well with carboxylic acids [73][74][75], amines [76][77][78], aniline [79] and thiols [80,81], with several species also crystallographically characterized.…”

Cancer remains one of the leading causes of death worldwide. The interest in organometallic complexes as anticancer drug candidates continues to be pivotal for many researchers. Initially underestimated for their therapeutic potentials, rhenium complexes are now slowly gaining momentum. While tricarbonyl complexes of rhenium are widely investigated, dicarbonyl derivatives of the cis-[Re(CO)2]+ core remain largely unexplored. In this study, we tested in vitro a variety of rhenium dicarbonyl complexes for their activity towards three cancer cell lines (A549, MCF-7 and HCT116) and one healthy cell line (HEK293). The most lipophilic compounds showed, like the tricarbonyl species, good activity against specific cancer lines (IC50 = 1.5–2.5 µM); however, the same were also toxic towards healthy cells. In order to understand these differences, we performed a reactivity study of cis-[Re(CO)2(NN)]+ species (where NN = diimine) with biologically relevant functional groups (-COOH, -NH2, -SH and aromatic nitrogen-based ligands) and compared the chemistry to what is known for the fac-[Re(CO)3]+ core. Overall, we found that the rhenium dicarbonyl complexes only show good reactivity with aromatic nitrogen-based ligands. The reaction of cis-[Re(CO)2(NN)]+ species with common bio-functional groups leads, rather, to the formation of bis-diimine dicarbonyl complexes (cis-[Re(CO)2(NN)2]+) as the major by-product.
