I am concerned that this article no longer meets the good article criteria due to uncited statements in the article, including one tagged as such since 2016. There's also some other tags in the article that should be resolved. Is anyone interested in resolving this concern, or should this go to WP:GAR? Z1720 (talk) 03:30, 14 January 2025 (UTC)[reply]

Recent work has reported a copper(-I) compound and so the infobox should be revised to add this to the list of oxidation states with the following paper cited https://doi.org/10.1038/s41467-025-56544-z Jackson, R.A., Evans, N.J., Babula, D.J. et al.
