Abstract
UNDER the above title, Glueckauf and McKay1 have presented a discussion, based in part on data of Katzin and Sullivan2, in which they suggest that the co-ordination of nitrate groups, and the extraction of uranyl, neptunyl and plutonyl nitrates into organic solvents, are phenomena different in kind from those found with elements lower in the periodic table, and are therefore indicative of possible f-shell covalency. I believe that the co-ordination of nitrate by uranyl ion is neither unique nor different in kind from that found lower in the Periodic Table, and in particular with a transition element such as cobalt.
