Complexes of cis -dihalogenorhenium(V) with iminophenol

ReVO and ReVNPh complexes with pentadentate benzamidines – Synthesis, structural characterization and DFT evaluation of isomeric complexes

“…Nevertheless, hitherto there is only a limited number of structurally well-characterized rhenium or technetium complexes with pentadentate ligands reported and particularly such compounds were not in the focus of related nuclearmedical research [9][10][11][12][13]. This may possibly be understood by the fact that the syntheses of pentadentate ligands are frequently related to multi-step procedures, which are too time-consuming for the preparation of only one single molecule with uncertain biodistribution features.…”

“…1 H NMR (400 MHz, CDCl 3 , ppm): 1.41 (t, J = 7.0 Hz, 6H, CH 2 CH 3 ), 3.60 (s, 6H, NCH 3 ), 4.40 (q, J = 7.0 Hz, 4H, CH 2 CH 3 ), 7.3−8.1 (m, 18H, Ph). 13 C NMR (400 MHz, CDCl 3 , ppm): 14.40 (OCH 2 CH 3 ), 41.94 (NCH 3 ), 61.23 (OCH 2 CH 3 ), 124 N-(4-Ethoxycarbonylphenyl)-N-methyl-N′-benzimidoyl Chloride (8). The synthesis of 8 was adopted from the general procedure.…”

“…X-ray crystal structure shows, that the bonding distances and angles in 1 and 2 are nearly identical, and that the two halide ligands in each complex are coordinated cis to each other in the equatorial plane cis to the oxido group. Rhenium(V) complexes with two iodido ligands cis to each other are rare (Abrahams et al, 2007).…”
