| Jan 18, 2015 at 17:39 | comment | added | LDC3 | @Self-teachingDavide Since $UO$ exists as a compound, then $UO_2^{2-}$ can also exist. webelements.com/compounds/uranium/uranium_oxide.html | |

| Jan 18, 2015 at 16:25 | comment | added | M.A.R. | Now that I think about it, I see that two brackets like this ][, if not awkward, would've looked way messier than a | . Maybe it was the author's or the publisher's attempt to make chemical formulas look a little bit neater. | |
| Jan 18, 2015 at 16:15 | comment | added | Self-teaching worker | @MARamezani Thank you again! I've just found other similar formulas in Mottana-Crespi-Liborio's text: Cu[UO$_2$|PO$_4$]$_2\cdot$12H$_2$O for torbernite, K$_2$[(UO$_2$)|V$_2$O$_8$]$\cdot$3H$_2$O for carnotite... but UO$_2$ is cation UO$_2^{2+}$, not an anion. Therefore my initial supposition that the brackets contain anions was wrong... | |
| Jan 18, 2015 at 15:24 | comment | added | M.A.R. | Maybe, and I say maybe, they wanted to demonstrate something like, for example, brochantite has $\ce{OH-}, \ce{SO4^{2-}}$ and copper. | |
| Jan 18, 2015 at 14:16 | comment | added | Self-teaching worker | @MARamezani Thank you very much for the comment! I've found this particular formula in an Italian language book: A. Mottana, R. Crespi, G. Liborio, "Minerali e rocce" ('Minerals and rocks'), but I've found similar notations in several other books of earth sciences. | |
| Jan 18, 2015 at 13:32 | comment | added | M.A.R. | I'm not sure but wikipedia has just written a normal formula for Brochantite: $\ce{Cu4SO4(OH)6}$. Could you give me some reference of where you saw that formula? | |
