Na(H2O)6{H2O}6(SO4)2 ?
User:Piledhigheranddeeper placed a question regarding whether the anion Na(H2O)6{H2O}6(SO4)2 should have a charge sign. I am quoting directly what the source says, mentioned in the abstract. If anyone else has any input, it is welcome. Chris857 (talk) 23:28, 23 May 2012 (UTC)
 * Don't have access to the article, but the formula as written would seem to need a charge as it contains one Na+1 and two SO42- as well as being an anion sheet. Rather than "quoting" (as you say) from the abstract, you should see what the body of the article says to clarify. I'll comment out the questioned sentences until clarified. The info should be in a Structure section rather than a general "Description" section with further expansion from the cited article. Vsmith (talk) 02:14, 24 May 2012 (UTC)
 * OK, here's a link to a pdf of the article. Vsmith (talk) 02:24, 24 May 2012 (UTC)
 * And the article specifically states that the sulfate bearing "sheets" have a 3- charge. Vsmith (talk) 02:32, 24 May 2012 (UTC)

I just want to mention that mineralogy isn't anywhere near my area of specialty, but I recently found that I can write on minerals (and there are many redlinks out there). The description of the details of the structure are too deep for me, so I will leave that bit to you ( and others ). Chris857 (talk) 02:57, 24 May 2012 (UTC)
