About LipscombiteHide

08685100017271924916583.jpg
William Nunn Lipscomb, Jr.
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+/∑Fe 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 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 “for his studies on the structure of borates illuminating problems of chemical bonding”.
Dimorph of:
Isostructural with:
May be confused with its monoclinic-pseudotetragonal dimorph barbosalite.
