Correction to: Nature Communications https://doi.org/10.1038/s41467-023-37802-4, published online 24 April 2023

The original version of this Article contained errors in Table 1, where: the second, third, fourth, fifth and sixth entries of the fourth column (DFT-calculated peak position (ppm)) were incorrectly given as ‘+261 ~ +291’, ‘–29.1 ~ –36.0’, ‘+135 ~ +601’, ‘+192.2’ and ‘+208, +202’ instead of the correct values ‘+269 ~ +270’, ‘–29.1 ~ –36.8’, ‘–57 ~ +80’, ‘+145’ and ‘+47, +49’; the third and fourth entry of the fifth column (DFT-calculated |CQ| (MHz)) were incorrectly given as ‘0.36–0.90’ and ‘5.1–10.7’ instead of the correct values ‘0.36 ~ 0.90’ and ‘5.1 ~ 10.7’. This has been corrected in both the PDF and HTML versions of the Article.

The original version of the Supplementary Information associated with this Article contained errors in the legend of Supplementary Figure 7 and in Supplementary Table 4. In the legend of Supplementary Figure 7 the figure panels were incorrectly labelled as ‘a,b Nb’ and ‘c,d Mo’, rather than the correct ‘a,b Mo’ and ‘c,d Nb’. In Supplementary Table 4, the second and fourth entry of the fourth column (DFT-calculated δiso (ppm)) were incorrectly given as ‘–848 ~ –890’ and ‘–867 ~ –898’ instead of the correct values ‘–848 ~ –862’ and ‘–867 ~ –897’; the first and fourth entry of the fifth column (|PQ| (MHz)) were incorrectly given as ‘18 ~ 27’ and ‘41 ~ 68’ instead of the correct values ‘18 ~ 20’ and ‘41 ~ 50’. The HTML has been updated to include a corrected version of the Supplementary Information.
