“…The origin of the perrhenate anion in 1 is probably due to the oxidation of a portion of the [ReO 2 (py) 4 ] + starting material during its reaction with H 2 L 3 . This phenomenon has been observed previously for both rhenium(V) [6] and technetium(V) [7].…”

“…The state of the art in this field recognizes the concept of a mixed ligand in either the "n + 1" or the "n + 2" proposal as a suitable approach. In these complexes, n coordination positions are occupied by one ligand, which provides a stable structure to the [Re V O] 3+ core (3), whereas the other ligand, also called a coligand, completes the coordination sphere. The physicochemical properties as well as the redox behavior of the resulting complex can be modified by changing the nature of the coligand (3)(4)(5).…”

“…The preparation and characterization of Re complexes with structure [ReO(dien-H)(aa)] + (dien-H = NH 2 CH 2 CH 2 NCH 2 CH 2 NH 2 ; aa = amino acid) have been reported in the recent literature (3). Crystal structures of these complexes show a deprotonated dien occupying three equatorial positions and a deprotonated amino acid coordinated through the amine and the carboxylate groups (3).…”

“…Crystal structures of these complexes show a deprotonated dien occupying three equatorial positions and a deprotonated amino acid coordinated through the amine and the carboxylate groups (3). An important feature of this spatial configuration is the location of the amino acid carboxylate, which occupies a position trans to the oxo group in the octahedral.…”
“…[ReO 2 L 2 ]I (L ¼ en, dien, trien, tren) and [ReO(dien-H)(val)]I were prepared as previously reported [26,27]. Bovine serum albumin (BSA), 67,000 Da, fraction V, was purchased from Sigma (USA).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
