About Lipscombite
Formula:
Fe2+Fe3+2(PO4)2(OH)2
Lipscombite from the type locality appears to be Mn2+>Fe2+ (but based on a pre-microprobe analysis that even its authors remark might be a bit "iffy" with regards to an accurate Fe3+/âFe ratio). Also, the literature describing lipscombite from other localities have not been evaluated here (yet) for any analytical data that might indicate their Mn2+/Fe2+ ratios; hence, the possibility exists that the Fe2+-dominant composition for which the mineral is officially defined may only be known from synthetic material.
Colour:
Black, dark greenish, olive-green, pale greenish, yellowish brown
Lustre:
Sub-Adamantine, Vitreous, Waxy
Specific Gravity:
3.66
Crystal System:
Tetragonal
Name:
In honour of William Nunn Lipscomb, Jr. (9 December 9, 1919, Cleveland, Ohio, USA - 14 April 2011, Cambridge, Massachusetts, USA), American inorganic and organic chemist, University of Minnesota, Minneapolis, Minnesota, USA, who determined the crystal structure of the synthetic compound. The name was originally given to synthetic material. Lipscomb was awarded the Nobel Prize in Chemistry in 1976 âfor his studies on the structure of boranes illuminating problems of chemical bondingâ.
