" linked together by the interstitial complex {Ca3(H2O)17}6+"
This phrase, copied from the crystal structure article, is misleading. It is not a single complex. Rather there are calcium ions with a variety of water molecules attached to them, formula [Ca(H2O)n2+. These are hydrated calcium ions, not a "complex" as the the calcium aquo ions cannot be bound together. I would not even describe the Ca ions as interstitial. The compund is a salt of formula ([Ca(H2O)n])3(V10O28). Petergans ( talk) 10:48, 16 July 2012 (UTC)
Why is this a notable mineral? Does it have any uses or "do" anything? Is it important because it's rare? Hires an editor ( talk) 11:54, 16 July 2012 (UTC)
It appears to be extremely rare, and cool looking because it fluoresces Rgambord ( talk) 14:56, 16 July 2012 (UTC)
