I don't think there is nickel in phosphomolybdic acid!!! Please correct it!!!
- You're correct. I have replaced the incorrect data in the infobox. --Ed (Edgar181) 19:28, 23 September 2007 (UTC)
A picture of the structure of phosphomolybdic acid is online (but may be copyrighted)[1] ; it has the "Keggin" structure also shared by phosphotungstic acid. The general formula for the structure is as given on the page, in which M = Mo, X = P: H3PMo12O40. As prepared it is a yellow powder with a variable number of waters of hydration; for this reason it is typically listed in chemical catalogs as "H3PW12O40 • x H2O". It is also easily synthesized; see for example [1]. "Keggins" are also a general name for many other structures that comprise cages formed from corner-sharing and edge-sharing MO6 octahedra. The link given above has a discussion amenable for use in expanding this page, if one wished to inquire about permission to do so.Rowanw3 (talk) 01:13, 3 November 2009 (UTC)
