Abstract
Correction for ‘Exploring the use of rigid 18-membered macrocycles with amide pendant arms for Pb(II)-based radiopharmaceuticals’ by Charlene Harriswangler et al., Inorg. Chem. Front., 2024, 11, 1070–1086, https://doi.org/10.1039/D3QI02354K.
The authors regret that the reference used for the 207Pb NMR experiments was incorrectly reported in the original manuscript, while the chemical shifts are correct. 207Pb NMR chemical shifts should be referenced to Pb(CH3)4 and not 1 M aqueous Pb(NO3)2, as is stated in the text. Therefore, the first section of the second paragraph of page 1075, relating to the 207Pb NMR spectra should read:
“The 207Pb NMR spectra of the complexes display signals in the range −2178 to −2255 ppm, referenced to Pb(CH3)4, with the cyclohexyl derivatives providing slightly more negative chemical shifts and the glycinate derivatives slightly more positive shifts (Fig. 4). The similar δ values observed for the four complexes point to comparable Pb(II) coordination environments. The 207Pb NMR signals observed here are shielded by ∼1500 ppm with respect to those reported for EDTA derivatives60,67 and [Pb(DOTAM)]2+.68 Similar negative chemical shift were also reported for complexes with crown ether derivatives.64”
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
